The bug-report was delayed for greylisting by gnupg.org servers but was
eventually accepted, but appears to have gotten stuck; hopefully it'll
make it through at some point?

Short version: macOS doesn't include /etc/nsswitch.conf and GnuPG's
dirmngr is hard-erroring when that file is missing, such that no DNS
operations succeed and --recv-key returns ENOENT type errors to the
caller.
