Well, sure, but if we mean "not enforced, just message-passing style instead of shared memory", then half the kernels classified as monoliths might count as microkernels. That was one of Armstrong's interesting observations: sometimes message-passing can be much faster than sharing memory if passing a message lets you avoid locking, and his system has all of these immutable data structures so you don't even have to copy or copy-on-write, you just pass a pointer.

This is how Erlang is intended to work as well. I think this is how good systems tend to work.
