When I started working on the kernel in the 1990s, it was "the most
technically correct approach of competing approaches".  If we've
now switched to "first received, first applied" that can only be
harmful and demotivating to those who wish to do a good job.

If someone has a better approach ready to go, why should the
inferior approach be applied and then the better approach have to
be rebased on top of the inferior approach?  This makes no sense.
