As you wish, I am no longer going to debate the pedantic meaning of pure microkernel ideology.
I rather be happy for the improvements in the long term roadmap and overall outcome for the eco-system.

If you just consider disallowing 3rd party modules to be a "microkernel" all while the kernel itself still loads most if not all (approved) drivers such as PCI bus, storage devices or filesystems in the same address space, then _all_ current major operating systems are "microkernels".
What you call a kernel like that?
Locked?
"A kernel that only allows user-space third party drivers"?
That this style doesn't have a nifty name isn't a good reason to weaken the established definition of microkernel just so it does.
So, then it becomes a balancing act how many are allowed the priviledge to be part of the main act.
Well, that is kinda the point of a microkernel (or at least one of the points).
Sure, you're not going to have a kernel whatsoever without say an CPU/MMU driver in the same address space. Maybe a driver for the timer.
But when you have graphics, sound, storage, USB controllers, filesystems, networking and most of a BSD kernel (providing all the syscalls) in the same address space, now that is not a microkernel by any definition of the word.
XNU is called an "hybrid" kernel in part because in the original design the BSD parts implementing most of the actual system could have been spun off as a separate process (similar to Windows NT's original design), which would have been an actual microkernel, but in practice they were just stuck together in the same process, making it a monolithic kernel in all but name (just like in Windows).

Yes.
Which is what pjmlp implies, once they are out, isn't it microkernel?
This isn't pedantic, nor is it ideology. If you're acquiescing, do it graciously and please refrain from name calling.
From all purposes from a third party driver writer persona, the only path forward are user space drivers.

This is basically calling me silly, just as you were calling the previous person ideological and a pedant. If you cut out this commentary that would be great.
