It's just tradition. Some other seldom-used signal could have been
chosen, but way back when somebody chose SIGHUP, and other people
followed suit.

Not intrinsically. It's just a convention in the Unix world that
sending SIGHUP to a daemon will cause it to re-read its configuration
files.
I presume that automagically reading them any time they changed was
both too much hassle and possibly dangerous: if a file is being
edited, it might get saved in intermediate (broken) states during the
editing session.
