If this is indeed intentional, I think the intention is wrong. Since we
don't package TeX, we know that we are using the system TeX, and so it
should be launched with the system environment.

I need to run xelatex on the produced source anyway, since lilypond-book
doesn't do that for me. However, this doesn't provide a workaround:
lilypond-book needs to successfully run xelatex in order to determine the
line width for producing the snippets.

Yes, xelatex by itself works fine. Lilypond-book works fine with xelatex if
I compile it from git (which is what I usually do). It fails when I install
the prebuilt packages (tested with 2.14 and 2.15). By the way, this is not
specific to xelatex; I have the same problem with normal latex, but it
happened that the file I was working on last week needed xelatex.

Presumably. For my personal use, I can just compile lilypond from git and
then it just works. I really just reported it because I think that it's a
bug and I thought it might eventually affect someone else.
