Yes, working through a third-party cloud is not ideal, but I have not seen anything that matches the price/simplicity and is self-hosted.
Regarding security, I don’t have it so I can’t confirm it 100%, but it’s not supposed to override the traditional key or block the handle, so you shouldn’t have that problem.





Aside from the opinion on whether that would be good or bad, I think the infrastructure wouldn’t be able to absorb so many users in such a short time, unless many of them host servers, something that seems unlikely, even if they donate to existing servers I think many would crash or the admins would be overflow
