I don't think I'd say rarely. Companies rarely allocate the design resources to produce that, but the companies that do are typically much larger, so the actual number of individual developers that get rich mocks is probably closer to 40-50%.
I’d say rarely in the sense that out of the 500 times (not really that much over 30 years) I’ve built similar things, I got UX mockups this detailed maybe 10% pf the time.
