A combination of history (the world was an uglier place before we
got dhcpd to talk to postgres), trying to make the virtual device
small (so not putting dhcpd, postgres client libs etc. on it), and
trying to isolate the virtual device from databases with useful
information in to limit the damage if it did somehow get hacked
(as there's not a lot of damage you can do if you can only send
dhcp packets). But yes, that's something we may revisit.
