Thank you very much as always for your hard work.
As for your question, I believe there is no problem with merging pull requests that involve obvious fixes, such as fixing CI failures, into stable branches.
I asked @usa (Usaku NAKAMURA) and @naruse (Yui NARUSE). old stable branch like ruby_3_1 and security maintenance branch like ruby_3_0 remain the current workflow that is I submit a pull-request or patch, usa will merge it.
I try to fix CI failure only stable branch like ruby_3_2 at first. Thank you.
