With any luck we'll be able to build a platform specification that allows both of these systems to exist -- essentially "boot Linux into M-mode" or "boot Linux into S-mode".  It'll be work to make sure the spec can work for everyone, but that's part of the way to get a good spec.

There needs to be some slight barrier to entry, some commitment
needed, otherwise the process has a real danger of simply being
flooded by concern-trolls and time-wasters and never completing.
Designing things by discussion and consensus rather than simply having
a completed spec handed down from some expert is already
time-consuming enough.
