"During the first Toronto hackathon, I focused on the SQLite database backend for mandocdb(8). Currently, mandocdb is still disabled in OpenBSD-current, but it is intended to become a drop-in replacement for the makewhatis(8) utility, providing enhanced search capabilities for the apropos(1) manual page search utility".
This made jump up and down, as a UNIX user on many different platforms I'm ecstatic that such core system tools and utilities are being actively maintained and expanded. Thanks to the "Not maintained here, let's borrow it," effect, in a few years other systems I'm subjected to will likely have a apropos command that's seen some development since the '80s.
