Because experimental is for stuff that is not yet ready for end users.
It can't be reliably used to feed a rolling release that is supposed to be

I'm not disagreeing with the release team on that. It's the current
situation and we have to live with it.
That does not mean we should not discuss other ways of dealing with
the release process if rolling was already existing.

I don't want that necessarily. I'm thinking out loud with you all to have
ideas of what could be done. Then we have to decide something.

Why "clearly" ? If we want a usable release that contains fresh
software, we need a place where we upload packages that are supposed
to be of release quality. That place is unstable currently.

I don't follow you. The rolling release would continue to behave like
testing after the freeze. Only versions aged enough without new RC bugs
would migrate to it. Manually asking users to install is cumbersome and
doesn't bring enough testing (I tried several times and defects were only
found once the package hit unstable).
