There are two main audiences for stable branches:

* Downstream consumers.
* Upstream developers working on master who need a working stable branch.

I cannot comment on how well the first group is being supported. But as a
member of the second group, I am constantly frustrated by how frequently
broken stable branches ruin my day.

I don't think its reasonable to assume maintaining the stable/branch
excludes actively supporting and improving are testing harness and related
tooling. Our tooling is constantly changing and supporting stable branches
means working on our tooling to make sure its functioning as expected for
stable branches.

Also cutting a new release of a library is not a 'change in tooling'.

Where is it documented that Adam is the Juno branch champion and Ihar is
Icehouse's? I didn't see it anywhere in the wiki.

If something breaks in stable/juno and grenade on master seizes up, what
should we do? When issues are blocking development we should not have to
wait for any one person to respond -- single points of failure are bad. So
I don't think 'has anyone tried to contact us' is the right question to
ask. A better question to ask is 'have stable branches recently prevented
development'

So who should I contact to help me freeze all stable/* dependencies? Or
better yet, someone to drive the effort instead.
