Thank you for your example.
At least I now understand (roughly)
what all the philosophical discussion was about.
However, I am still puzzled by the purpose of it all.
The new xr.sty is manifestly more difficult to follow
than its predecessor.
So who is meant to benefit ?
The user, the package writer, ... ?
And what exactly is the benefit ?
(I'd be grateful for an explanation not using the word "module",
which makes my head dizzy.)
