Maybe if they're posted again and again, they're real pain points and should be addressed?
No obviously not. They are just easy to bring up without ever engaging with the actual material.
I say this as someone who has used GIMP for two decades now. It was the first real image editor I used, so the UI/UX is fine to me, but it's clearly a problem.
GIMP is steadfast about the name, but has been slowly incorporating UI/UX improvements since its existence. (Single window mode, canvas rotation, more consistent UI on Macs with 3.0, high DPI support, etc.) GIMP doesn't have raw support yet, but it does have high bitdepth support (both integer and floating point).
The whole point of GIMPShop and PhotoGIMP are to address these pain points.
