You're taking that the wrong way.
I think defining custom functions precisely helps maintaining large
scores. Let me tell you about a personal example. In a very large score,
I wanted tempo markings (Allegro...) to be written like this:

\mark \markup { "" \translate #(cons -3 2) "Allegro" }

What I did was to define a custom function, \tempoMark, invoked like
this: \tempoMark #"Allegro"

But some day, \markup { "" \translate ... } stopped working as before,
and had to be changed to: \markup { " " \translate ... } (note the space
between the double quotes.) This was simply done by just changing the
custom function definition, not the 148 places were \tempoMark was used.
