Is MirageOS used in 'production' systems anywhere at any significant scale?

Not asking to be antagonistic, asking because I think unikernels are really nifty, and genuinely curious if they've worked out for anybody.

It was being used in production on TI-84+ [1], haha

The libraries are embedded in quite a few places; for example it's used in every single Docker for Desktop instance:

And then there are deployments in QubesOS, Xen, Nitrokey, etc. Bear in mind that MirageOS is a library OS, which doesn't just mean "compile to a standalone kernel instance". It just means that it can be linked into all sorts of embedded environments, some of which are the solo5 or Xen backends you see in talks.
