I'm ambivalent about the proposed user-interface change.

I understand the argument about the behaviour being closer to what
(Linux) sysadmins expect, but don't forget that such Linux systems
usually don't install the rc.d script for an uninstalled service,
and they usually automatically start and enable a service upon

(This difference of behaviour with Linux (not that there was any
reasonable consistent standard in UNIX when we developed rc.d(8))
is why the directory is /etc/rc.d and not /etc/init.d.)

Having the ability to control whether the existing NetBSD practice
or your proposed practice (via an rc.conf(5) var?) may be useful.

Have you considered discussing this with the FreeBSD folks, since
they use a derivative of rc.d(8) in their system?

In any case, _if_ this change is performed, it should be noted in
an obvious place as a "Behaviour Change" so that people don't get
bitten as easily. (I.e, don't just commit changes to rc.subr and
rc.conf.5 and note the change in para 5591 of the release notes :-)
