Does anyone know if Adobe ever plans to add more lens profile support for Fuji XF lenses. The only lens I see supported in LR5 is the 23mm on the X100. I have downloaded all LR updates except the latest that just came out.

I don't see how anyone here would know what Adobe plans or doesn't plan to do.
What I do know is Adobe reads the XF lens correction parameters for vignetting, transverse chromatic aberration and barrel/pin-cushion distortion stored in the raf raw file metadata. These correction parameters are computed by Fujifilm's lens designers. The correction parameters are stored in a firmware chip on-board each XF lens. When a raf is rendered in ACR or LR, the parameters are automatically applied to the image.
So Adobe likely figures it's redundant to develop their own lens correction parameters. This is very different from Nikkor lenses because Nikon's lens correction parameters are proprietary. The only way you can apply Nikon's lens corrections is to purchase Nikon's software. For this reason Adobe provides correction Nikkor parameters from their own optical tests.
The X100 does not have on-board lens correction parameters. This is why Adobe includes a X100 correction set. I do not know anything about the X100S.
Anyone with a computer can compute their own supplemental XF lens correction parameters using free tools available on Adobe's labyrinth-esque website. The utility of these parameters depends greatly on the skill of the person who computed the parameters.

Thank you
Thank you
Thank you for your explanation. I didn't know that. I have wondered because they had the X100 23mm lens profile and scads of profiles for my Nikons and every other brand of lens out there, but there were never any updates on the new Fuji lenses.

Good initial question and good answers...
So the high gain question is:
Has anyone here created a set of Fuji profiles with the Adobe tool? Do you like them? Would you be willing to share them?

I have read elsewhere that people have created Adobe profiles to supplement the on-board, automatically applied profiles. But I never paid attention because the quality is difficult to evaluate without doing tedious testing.
The Occam's Razor answer is the Fujifilm parameters should suffice unless there is evidence that says the solution needs to be more complicated.
The 18/2 XF lens requires very large barrel distortion correction parameters. The lens does have issues at the extreme frame edges when highly structured content present. The first order barrel distortion corrections parameters are not sufficient. The result appears to be CA… but it's not. The ACR/LR Defringing and Clarity sliders often minimize these artifacts. Otherwise, the Fujifilm profile works well.
Occasionally there is residual transverse CA in 18/2 images that requires tweaking in LR. Even silly levels of pixel peeping does not reveal transverse CA for my copies of the 14/1.8, 23/1.4 or 35/14 XF lenses.
