What issue?

What bugs regressed?

I don't see the problem here, other than a low-quality of patches that
need reworking for some patchsets, and others are just fine.  Just like
all kernel subsystems, I don't see anything odd here.

That's not how any of this works :)

That's generous, but how about doing review first, the maintainership of
this subsystem does not feel like any sort of bottleneck to me.  I
personally have no problems with Moritz's interactions with the
community, his reviewing of patches, and forwarding on to me.

Of course we all have delays as we have other work to do than just this,
that's just part of normal development.  I don't see anything stalled at
the moment, nor anything that having another maintainer would have
helped out with at all, so this feels like it is not needed from my end.

Again, it feels like the developers need more reviews, and good ones, so
please continue to help out with that, as that's the best thing I can
see to do here.

thanks,
