I'm working on some ideas that require breaking changes with vmm(4)'s
ioctls. We haven't made many breaking changes recently, so I wanted to
put out a feeler for folks to speak up if they're building on the API
defined in vmm.4.

In the past, there was a hypervisor (written in ocaml I think?) that did
this but since dropped support for running natively atop vmm(4).

Give a shout either directly or on list. I'm happy to work with
developers on this as it provides a good feedback signal on if my ideas
cause too much friction and how to improve the design.
