Yup. Sometimes it's difficult to see "at the current moment", though.

They don't have to hold off new code, though. There is always a new
unstable ready to accept those things. The problem is, as you say,
balancing the length of the freeze. You want it long enough to fix
the important bugs but short enough for things not to get out-of-date.

It would be great if big changes like that always happened at the start
of a freeze, but applied _only_ to the new unstable. That would give the
maximum time for it to stabalize before the next freeze. As RM, you get
a lot of complaints from people who want their package installed, so you
need a pretty thick skin.

That's reasonable. In fact, I don't think anything else is really possible.
Even without that as an official policy, it's still what happens in practice.

Right. You can't update a library for the sake of a derivative package.
That's just asking for trouble. (And Murphy is usually listening.)
