Okay ... more evaluation, experimentation.
On yesterday's walk, I decided to take the Pixii fitted with the MS Optics Aporia 24mm f/2 lens.
In the course of yesterday's shooting, the Pixii displayed "Fault" a few times and required powering off, then on again, to clear it. I was rather capriciously flipping around between various menu settings as I walked and I might have also inadvertently knocked the main time wheel (on top) off the Auto setting or even between setting clicks. The A-Lock function might prove useful to prevent this for me for this kind of casual walking about situation.
The various in-viewfinder displays affect me the same way they do for most cameras .. I dislike them. I mostly like using the aperture priority automation, controlling exposure with the EV compensation, but I'd rather set my EV Compensation before making an exposure as I look at a scene and make a tweak one way or another. I'd prefer the exposure indicators to be a bit less fussy too.
I flipped back and forth between the Bayer and Monochrome modes a few times. I think that doing that is when I saw the Fault notice come up, primarily, and that's also when my exposure settings seemed to go off the rails most of the time. Certainly, more investigation and evaluation is needed.
I set the lens to f/4 for my walk and shot still life scenes, trees, and my usual oddities of found compositions. One thing I'm happy to report is that my Aporia 24mm focusing cam seems to be right on the money: Very good sharpness for every photo I made that I'd focused. It's the first time I've used this lens on an RF body and had heard various folks reporting some cam placement issues—happy to say it doesn't seem to be an issue with my lens.

However, looking at my exposures, it seems the Aporia 24/2 is not as good an optical match to the Pixii sensor as it is to the Leica CL sensor. At f/4, I expect a little corner and edge fall-off to occur, but on the Pixii sensor I see a good deal of color shifting as well as much more light fall-off than I see with the CL. The on-center sharpness is excellent, and likely would be at f/5.6-f/8 as well.
Here's a look at a simple snap of the clouds overhead, Bayer setting with standard color space, no processing on the image:

It's a mostly monochromatic image anyway, but you can see the magenta-cyan color shifting from center to edge easily. Slightly more successful, but the color shifting does intrude, is this photo of the pizza shop's table umbrella:

Switching to Monochrome mode, I must have inadvertently also switched the ISO setting and/or knocked the time control dial to a manual setting... Both of these were about 1-2 stops over-exposed. I kinda like the rough, hyper-contrasty rendering I was able to eke out of them, but I need to experiment with the Monochrome mode a lot more before I can rely upon it.

All in all, I'd say the Aporia 24 is best suited to the CL or M4-2 at this point, and not a good choice on the Pixii.
Another camera behavior I need to get more used to is the feel of the shutter button. It's a very light, somewhat numb feel ... The camera makes a quick noise simulating a shutter release which I sometimes hear and sometimes not, it also seems to make a single 'tick' with speeds faster than 1/30 second and a double 'tick ... wait a tenth of a second ... tick' for anything slower. The real problem is that with such a silent eshutter, the question of when the exposure has been made is a bit tricky. The tick noise doesn't really help in moments of high ambient noise (it's too quiet) and without a display LCD the only way to be sure you've made an exposure is to look at the exposure count on the top LCD. I'm pretty sure this is just a matter of learning and accommodation.
Today I'll either take the camera out for a walk with my loaned-for-evaluation MATE or the Summilux 35. More when...
