1. Go for it.
2. Let's see what the outcome is. How many 'merge races' we have, how many
regressions (hopefully none), how much work is poured into it,
Do you want for the new branch full CI coverage? Just branching takes a few
seconds, and almost no resources (except for mental ones, in developers'
minds). CI takes more time and more resources.
so we'll
learn from the future if we should branch sooner or is it OK to wait - and
until when.
We had recently a private discussion about this, with no final conclusion
AFAIR. I suggested (and repeat now) to fully automate this - so that project
maintainers have in the gerrit UI checkboxes for CI per branch. This definitely
takes time, and was considered not worth it, with the assumption that if we do
our work well, we almost never need z branches - that we should aim to push
and merge almost all the patches for some z version right after z-1 was
released, and not postpone this to later on, when we already want to work on
z+1 - and those late-comers that do want/need a branch should verify their
patches manually and not need CI.
