I think for a lot of PJ's of the 50's and 60's the main concern was reliability. Their cameras simply had to work, no breaking down in the middle of an assignment a thousand miles from nowhere.
Not that many PJ's had (or have) assignments a thousand miles from nowhere. Indeed, most never had/have a assignment out of town - the average paper will buy pictures from an agency if they need photographs from somewhere way out of their regular field of operation.
Reliability is relevant enough that almost everyone in the business carries a spare - you can't simply re-enact press photographs even if the camera fails. But as long as the paper can provide spares, long term reliability does not matter that much.
