It's not mandatory; you only need to define it if you want to be
able to stop an interpreted daemon using the default method.
If you have some other way of shutting down a daemon without knowing its
name and PID then you can just supply a stop function to do it.

That's not been my experience. Occasionally it might a bit harder to
customise the script, but that's outweighed by all the times an override
can be made cleanly in rc.conf, without having to modify an installed
script. I've found that practically all customizations can be done
through rc.conf, and the rest usually involve editing an existing
And rcng make it easy to keep multiple copies of the same rc file, you
can keep separate config and switch between them from rc.conf.

If the interpreter changes from python2.7 to python, you'd have to
change the shebangs anyway.
