Please distinguish one-time contraints from general process

Who keeps us from pushing to jdk11u?  We could do so.

I think the name 'critical' is bad, it is misleading. The second
tag is needed because we have two codelines, and want to
distinguish for which the downport request is made.

I think we should use jdk11u only for rampdown. So  patches pushed to 
jdk11u should be limited and well restricted, but not necessarily rare.
But yes, definitely less than pushed to jdk11u-dev.

If they are interested in a decent stable version, they should only 
get the repo at rampdown.
I think it's rather because people have certain processes set up, 
and jdk11u-dev is new. 
That again is a bad trigger for basic process decisions.

No. The jdk11u is a repository used for rampdown so that development
can be continued in another repository, here jdk11u-dev.
It is not a convenience for testers, it is to allow parallel work with 
two different intentions: development <--> stabilization.

Yes it updates both because others want it that way, but I tried to 
assure at least some stabilization before tagging.

Yes, the audience pushing to jdk11u should be smaller than that
pushing to jdk11u-dev.

People should test jdk11u-dev if they want to test more early.
Then they know they are testing an arbitrary development state 
and nothing in consolidation.

By the way, what is your "downstream"? Is it a repo that 
differs from OpenJDK (kind of as our SapMachine)?
Or is it just a repo that feeds your build/test infrastructure?
