A "Requires" tag, as a counterpart of the "Provides" tag. See the attached
patch for how I think the Linguistics module should look like.
This would take care that a certain package is loaded only when it's needed
(f. ex., in the Linguistics module, only one Char Style needs csquotes), and
that it is loaded only once, even if another module or LyX itself requires it
as well (which is not the case if you load the package in the Preamble tag).
I think this would be trivial to implement, using LaTeXFeatures::requires().

The problem is that we are not yet flexible enough.

Yes. Layouts could probably use the Requires tag as well (albeit the feature
is probably not as crucial there).
