I understand, but you have to draw a line somewhere.  The easiest place
to draw the line is 2.3.0-rc0.

Maintainers can already prepare branches with patches destined to 2.4,
and these 26 can be included there.  As far as you are concerned, if the
code is ready you can stop worrying about it.

The problem isn't non-maintainer vs. maintainer.  There was a dependency
on Igor's series, which took some time to get in---partly because it was
included in a 100-patch pull request, which isn't exactly the preferred
way to send pull request in absence of a serious effort on continuous
integration of maintainer branches.
