For what it is worth, I trust the downstream distributions to make this call. I expect that any/all stable patches accepted in a model where release notes are generated per-commit (Plan D) this ends up looking like the Redhat model where patches are bundled in. 

In general we should have care in accepting a stable patch. But as the PTL (and more generally as a core) asking me to determine when there is "enough patches to generate a release" is far too distribution/packager specific and subjective. I do not expect to be reaching out to each and every one to say "hey did you release?" This, in my opinion is not a reasonable ask. I do not know what justifies "time for a release" for Debian or Redhat or Suse or Gentoo ... Etc. Please do not expect the PTLs and Cores to become experts on each and every one of these. I expect the packager to be making the subjective call in the non-time-based model outlined.
