Does it have full support for all the kinds of stacks people are running on Linux today? Is there a robust ecosystem of MirageOS users online able to help troubleshoot issues from the simple to the arcane? Is it supported by VPS providers the world over?
Personally, while I doubt these are the case, having never heard of MirageOS before, I'm willing to be proven wrong. However, if the answer to any of these is "no", I have a hard time seeing how "just abandon Linux wholesale for NewShinyThing" is a viable option for more than a tiny subset of users. (Even if they're all "yes", it's still a wildly unrealistic expectation...)

No, of course not; the only thing that supports everything that Linux supports is Linux. But most use cases don't use every part of Linux.

I doubt it, but how do we get to there from here except by more users starting to use it?
> Is it supported by VPS providers the world over?
Yes, since what you build is just a VM image.

I don't disagree as such, but I do think that at this point building anything on these insecure foundations is throwing good money after bad / building castles on sand. Probably 95% of the time you build something that serves your present business purposes, accept a certain amount of insecurity, and get on with your life. But it's worth putting a bit of effort into looking for better ways to do things.
