I'm guessing that this means that there will be no ETA on getting the
patch system working again, as it relies upon Debian actually producing
a version of mariadb that *does* support TLS v1.2+ and I would guess
that Debian's policy that "stable" distros remain bug-compatible with
their original release will prevent them doing so, despite it being
a regression compared to Debian Buster.
