I also remind myself about this only when it's needed, but then it's always

OK, so to just get some more rapid movement, I've changed my mind a little
about this and I've marked in the commitfest as RwF, but I've fixed lots of
bugs since last reviews over period of couple months and turned this into
3rd party extension (it's available under
https://github.com/jakubwartakEDB/pg_stat_tcpinfo , supports BBR now and so on
). It seems that's a better vehicle for it. FWIW, we are already working as
making available through the standard repos.
