Well, if those become necessary I'll just have to add Mastodon, along with anything known too well, in the bin for government-ruined software and start using hidden services... I will never willfully comply to spyware, not even (read: especially not) government-approved ones.

I have no idea if Mastodon has any plans adding those to the instance software though... Probably will if they get lawfully obligated I suppose, but I still sincerely hope not (as I still also sincerely hope this proposal gets dismissed for the obvious contradicting privacy laws it breaks and the vulnerabilities of backdoors).
