This would complicate the code behind Inkscape and the user interface a lot. It’s not just having an option to enable raster editing, the entire program must be rewritten, because its not designed to do raster editing. If they started with raster editing, it would be lacking too and the horrors from users would never end. I rather want Inkscape stay focused to what its doing best.

Either use GIMP or Krita. There are already excellent or good enough image editing tools.
