As a potential measure of community support, the majority of PRs are now targeting the unity branch. In the past 30 days, 57% of PRs (75 out of 132) have been on the unity branch. It looks like it’s also trending upward, as the past 90 days show 49% of PRs (213 out of 436) targeting the unity branch.
# Main branch

# Unity branch, excluding main
$ git log --after='2023-08-27' --oneline unity ^main | wc --lines
75
With that in mind, I’d view the unity branch as the de-facto main, and would support the T1 approach to make it be the actual main branch as well.
