IMHO it is just run for legacy compatibility.

I'd suggest: remove rc.local from the default install, and at the end of
startup/beginning of shutdown run it, if existent, unconditionally.

If you have anything depending on something else, you shouldn't put it in 
rc.local, but create your own rc.d script for it.
