I agree.  :(

If you really want to poke the hornet's nest, and if the scheme
implementation can be used for any arbitrary lilypond file (i.e.
just by adding an \include "new-overrides.ly" to the top), then we
could ask on the lilypond-user mailing list.


Since we'll be having a release candidate as soon as Mike fixes
his python 2.4 problem in output-distance.py, I'd ask you to wait
until 2.16 is out before pushing this change.  That's the only
real feedback I can give, sorry.
