Dovecot does not start on MacOS 12.01

I just upgraded to macOS 12.1, ran into this issue, and discovered this thread from the error message.

Is there a viable workaround or patch yet?

I tried the workaround in this thread, and still see these issues.

Set default_vsz_limit = 0 in ./conf.d/10-master.conf.

Observe that:
dovecot now launches without the setrlimit(RLIMIT_DATA, 268435456) error at the command line
However, the mail-err.log is still filled with these errors (below), perhaps for the child processes.
