The problem this thread is trying to solve essentially comes down to
"people don't do enough work and we want them to do more". There are
various factors at play here; time, motivation, demotivation,
knowledge, confidence and probably more.

The diversity of software in Debian is an advantage, I would prefer
that we strongly care about all packages for the release. I expect
that very few people in Debian and none/few of the QA or release team
members in recent years who share my opinion here though, I accept
that and avoid expressing this opinion in general. I also acknowledge
that we just don't have enough people to properly maintain all the
packages in Debian which means that my opinion is also unrealistic.

Agreed, I've been poking various RT folks about this over the years,
mainly I suggested completely automated removals for all packages.
That was a bit extreme though since core packages like
apt/toolchain/etc can have RC bugs open for a long time.

I think this is a much better idea than removals.

Agreed. Do you have any example use-cases that should block releases
but aren't in blends or tasks? Perhaps we need to start some new
blends or add new tasks.

piuparts folks generally already file RC bugs as they are able.

Ack.
