I wouldn't say it caps ceiling since nothing stops you from developing that side of things.There are lots of successful examples now, but let's not forget that mobility can cap someone's ceiling as well, to the extent that guys cover up bad habits or skill deficits by resorting to scrambling when they screw something up. Tom Brady became the type of quarterback he is in part (in my opinion) because he could not bail the pocket and run when things didn't go right.
But I do get the idea that since running QBs HAVE more margin for error they don't always continue to develop certain skills and habits because they don't have to, where a non-mobile QB either continues to develop those edges on he's falls out of the starting group.
I think to an extent it's probably just that mobile QBs can stay starter relevant longer with mediocre passing skills/habits because they have running to add, where a guy without running either gets better at all those pocket skills/habits or becomes a backup.
