Since \cadenzaOn effectively changes the time signature I wouldn't 
consider that an exception.

Which specifies the number of beats.

I haven't done this yet but the number of beats per bar is still well 
defined.  Is this documented somewhere?

So it could be reasonable to give an error when the number of beats/bar 
is exceeded (when not in a cadenza).  I would guess the present bar line 
logic already presents the condition where the error message could be 
added.  I have generated many pages of music without this feature using 
| when I need it but I can imagine it might help some users.
