Yes, I also don't like it. We have the same problem with
'info-file-dir' hook: it always pulls texinfo and gzip, but not all
profiles include info manuals.

It doesn't relate at all. This hook generates "fonts.dir" only for
"share/fonts/truetype" directory. Directories with X fonts are not
touched, because all sub-directories of "share/fonts/X11" already
contain "fonts.dir" files (font-adobe75dpi, font-misc-misc and other X
font packages install "fonts.dir").
'font-alias' package does not contain fonts.dir file because it doesn't
make sense: this package does not provide any font. It just installs
"fonts.alias" files inside "share/fonts/X11/{75dpi,100dpi,cyrillic,misc}"
directories. Eric made this commit for one particular case: to make it
possible to use font aliases in the default X server configuration
('xorg-configuration-file' in (gnu services xorg) module).
Just to mention, I think we shouldn't modify 'font-alias' package as it
leads to a bug <http://bugs.gnu.org/22100>, and should do some other
workaround. I have 2 ideas (not sure if they make any sense):
1) To add a special package (font-alias-with-fonts.dir) that will be used
in 'xorg-configuration-file'.
2) To do 'union-build' on packages with X fonts and aliases and to use it
in the X config. With this, we can revert that Eric's commit, and
everything should just work (I mean the X config will work and the bug
will be fixed).
