For me the more important part of the quiet period is that patches can't be
merged, so there's less urgency to review them immediately. So I think it's
fine to still send patches, but not having expectations about quick
response, as people might be taking time off.

On the other hand it would be better if new series could mature in this
quiet period, so there would be less work after rc1. But the key to making
that possible I think is to feel less urgency/being overwhelmed also in the
non-quiet period (rc1-rc5/6). Then it's should be less necessary to take
time off during the quiet period. So hopefully we'll get there through
involving more reviewers, and by having more submaintainers agency.
