Sensible.

It was only a couple months ago that David allowed  3\cm  to be used as a 
number within music.   Formerly it was allowed only in \paper {indent=3\cm} 
and other such blocks.

Only people reading this mailing list knew about it, none has said they 
use it, and I cannot imagine anyone else has stumbled upon it and started
to use it.  So there is nothing to document and no desired behavior for 
which to provide a work-around.
