Well, upstream doesn't support a pid file on purpose. (General
OpenBSD policy.) The argument is that the pid file construct is
inherently unreliable and dangerous: if the daemon dies, the pid
file remains and the pid may point to some random other process.

Yes, this is an unfortunate race. The fix would be to match the
process name against "ntpd: [priv]", the same way OpenBSD's native
rc script does. Unfortunately, this seems to be impossible with
rc.subr(8): only the first word of the process is matched against
procname.
I could override check_process; see below. Not sure how good or
bad an idea that is.
This is a general issue that should affect other daemons ported
from OpenBSD as well, e.g. net/openbgpd.
