The dh_installinit convention can be followed: default to using the
package name, but provide some way of overriding this.

Yes, but it is important that packages that get rebuilt continue to
function as before until they are updated by their maintainers.
That means that the "start" and "stop" arguments of update-rc.d must
retain their meaning.

Well, if the "factory defaults" are going to be merged with local
changes at run time then it would be best to put the former in /lib/
and the latter in /etc/.
If we decide to put dependency configuration in the initscript itself (a la LSB)
then a way of implementing the desired "factory default" files would be to hack
dpkg so that it extracts the LSB header information out of pristine
initscripts before considering whether or not to install them, and
stores this header in a standard place such as /var/lib/dpkg/init-deps/NAME.
