28mm prime is harder to sell than 35mm prime.
I think, this assumption lives from golden era of film P&S cameras. This days lots of compacts start from 28mm eq. FOV, 24mm isn't a rarity. Even moms like they can get all family at the table in a single frame.
As for enthusiasts, I think 28mm and around-45mm are much more popular than 35mm. 35 is a wild guess, stone thrown in a crowd, neither really wide nor regular.
