I think that last paragraph is the main point. Seeing as this was a suggestion
I think discussion about the possibilities at this point may be more useful
than just batting down the most obvious change.
If you don't like the suggestion, provide your own. Arguing about a
non-existent change seems counter productive. This is just an observation of
the direction of this thread, please don't take it personally.
I'm all for change towards a more modularised kernel. If there are stages that
involve larger kernels before we round trip back to smaller kernels, then so
be it. It seems that there would definitely need to be collaboration between
the various kernel devs to map out a more explicit path.
