No idea.

Well, documentation and code makes sense. But keep in mind that e.g.
kernel documentation is not scattered over src/sys. For the rc scripts
it makes a lot more sense to have them in one place, since they interact
with each other. I don't want to have to look over src/sbin/, libexec/ usr.sbin/
and where else just to find out which place I need to tweak to achieve a
certain order.

No such way. How should there? Also the stand-alone operation might not
be the prefered modus operandi, e.g. ftpd makes sense from inetd as

Depends on what you want. The activation flag is shown by $rc rcvar, but
the various configuration options for some scripts are certainly not
printed, if they exist. Typical examples are ${name}_flags, but other
much wilder example exists (e.g. consider netif).

That's also the reason why just masking them as options or so doesn't
make much sense, since the results of changes are too different to work
without specific handling anyway. Once you need the specific
case-by-case handling, the marking doesn't make much sense either.
