Are you sure this is what happened in the past? I mean I didn't
participate, so all I can rely on is git and the mailing list archives.

For 2.18, I see
 - release/2.17.29-1 tagged on 20 October 2013
 -

As far as I understand, stable/2.18 was created before 2.17.95 (which
was incorrectly released from master, see above). The merge base
between current master and stable/2.18 points to April 2014 which is
probably due to a partial merge? Certainly after 2.18.0 had been
released in December 2013.

For 2.20, I see
 - considerations in December 2016:

This looks like the release candidates (coinciding with the big bump)
have (or should have been) released from the stable/ branches?

That said, I'm not opposed to doing a pre-release candidate from master
and git history tells little about possible freezes. Just trying to
understand what might have worked in the past...
