question/suggestion MultiMeasureRests

[David Bobroff]

By default, LilyPond prints "church" rests for multimeasure rests of one
to ten measures rest.  From eleven measures up, it switches to this style:

|====== 11 ======|

I find that when I have a 10 measure rest I want to alter it which is
easily done.  I always change it because the church rests look odd to me
for more than nine bars of rest.  I concluded that they look odd to me
because I don't ever see them in engraved music.  To test this idea I
went through some of my collected orchestral parts.  Trombone parts are
chock-full of rests!  In only one instance did I see a 10 measure church
rest.  It was in an Edition Peters printing of "Die Schöpfung".  In all
other cases the church rests were used for up to 9 and then starting
with 10 the heavy horizontal bar was used.  The exception to this was
French music which used the heavy horizontal bar for everything more
than one.

My question:

Why is the default behavior to use church rests for 10 bars rest?

My suggestion:

Change the default behavior to print church rests for up to 9 bars rest.
