minimum-length has been a property of the engraver for a looooong time.
It never implemented the functionality you would expect from a minimum-length
property at other places of lilypond. Removing it would break older scores more
than necessary, so I strongly feel the need to keep it.

minimum-length in my patch means:
- Don't generated automatic extenders if it's impossible to give them 
minimum-length.
- Use minimum-length for forced extenders at unusual places (single note) if 
possible.

I think the most reasonable way is to keep that traditional name.
