I do not see the two methods as alternatives, but as complementary and
co-working: my proposal makes sure that a package works out of the box
by *prefixing* XDG_DATA_DIRS (and not replacing it). So a user is
still able to add themes in his own profile.

Or, do you see any problem? Or, would you prefer to append instead to prefix?
