I had exactly that: 2 _variables_.

I cannot have that (i.e. it's a personal choice to minimize the number of
changes from one project to another) because the "Staff" is exported from
the "contents" file: Hence at the score level, I just want to see a variable
"\staves" (which is a "StaffGroup"); but no reference to the internal
"drone" or "pipes".

Admittedly, there might be a better way to organize the layout/contents into
multiple files but if I'm not mistaken, there is a huge gap between the
examples in the manual or LSR (where everything is crammed into a single
file) and frameworks for large scale projects. [Some proposals have been
talked about in this ML (e.g. Nicolas Sceaux's) but they are not (yet?)
integral part of LilyPond.]
In-between these extremes, there are many different aproaches, but not one
considered to be the final "normalized" LilyPond template of templates...

Best,
