Actually doing that would not make the bagpipe stuff easier at all.
I currently have those commands in my bagpipe.ly file where they 
also set the key-signature-to-be-hidden by calling
  \set Staff.keySignature = #'((0 . 2) (3 . 2))

If the commands were moved elsewhere I would be forced to use a
different name, and I don't really want that since hideKeySignature
is exactly the right name even if it also silently sets the key
signature.

Keeping these commands in bagpipe.ly would ensure that we don't clash
with anything else. We can then assume that anyone who includes 
bagpipe.ly do want to write bagpipe music and that they are fine with
the "hidden" behaviour of also setting the key signature.
