This is a good example of this kind of evangelism for the hot new packaging standard gone wrong.
A pull request was made for a half-baked appImage version of OBS by appImage creators.
They refused to support it, and the OBS developers refused to merge it because they have no appImage knowledge.
Drama ensued.
I do like how nixOS is tackling this issue, but I don't really care enough to switch away from Arch.
