I don't have any expectations of them doing this (but I also have no expectations to the contrary), but I think it would be a good move from Red Hat to make the official RHEL more available, as you suggest.
In another thread I compared the RHEL rebuilds to piracy, and in that vein one could quote Gabe Newell and say that piracy is a service problem -- part of the reason Alma/Rocky/etc. exist is because there is a group of users who want to use RHEL but cannot afford it. Red Hat seems to believe that these users should be satisfied with CentOS Stream, and maybe most of them would be, if they only gave it a try. But making RHEL more widely accessible, both to paying users and developers, would probably be good too.
Gimp is just... not great. It's ten years behind the times. These days I tend to use Krita, even though it's more geared towards digital painting than general image editing.
