[query] [electron-updater] Why is a subset of linux distros supported for autoupdates?

[xyloflake]

So as the title states, I was looking for a solution to make auto-update work on platforms like arch linux. I read a comment made by @develar that it is by intention - that some platforms are not supported. However I failed to find any issue that mentioned the "why". I'd like to know why it is unsupported.

Thanks in advance!
