Unlikely to see wide distribution on Linux given the license

The license allows redistribution so I don't think it would be prohibitive to it being distributed.

Paint.net itself is still not open-source, so no distro will distribute it.

If this shin even becomes "good enough" then I'm sure it will appear in the AUR and flathhub, however.
