Isn't this exactly what ansel tried to do?

Not only that. I'd like to have AI masking, effective clone tools, lens corrections and please... actually working defaults! You import RAWs (compressed RAFs) and it render horrible results!

Its bloated with useless functions, it's slow, UI is ugly... Why not focus on important? Stop developing another demosaic method and make it more user friendly, less nerdy piece of tool.
