I agree, but I don't know whether others have a use for it. But if it's 
possible to have it controlled by a context property, as Simon 
suggested, that's even better. Also, convert-ly would be happy about that...

OTOH, IMHO, your idea is the one and only sane default. And I actually 
think that, per default, extenders everywhere should be automatic 
(although that might be a change that is not automatically convert-ly'able):
I've seen too many Lily engravings on CPDL et al. where missing 
extenders make the difference between a "perfectly usable (though still 
tweakable)" and a "confusing, but better than nothing" score. They have 
clearly been created by motivated, but inexperienced users who simply 
lack the awareness or the know-how to add them.

Found one more: http://lsr.di.unimi.it/LSR/Item?id=1006
A special situation anyway, but still valid.

Sounds good.

Of course, no hurry; didn't mean to make you work overhours in your 
spare time. ;-) I just wanted to get this out of my head and into the 
wild before I forget.
