Hi!

It=E2=80=99s mostly on a case-by-case basis.

An important criterion to decide whether to add an optional dependency
or feature is its popularity over extra-space ratio.

For instance, I suspect Wayland is not used much with Guix.  Thus, we
should check how adding Wayland support affects the size of Mesa=E2=80=99s
closure, using =E2=80=98guix size=E2=80=99:

  https://www.gnu.org/software/guix/manual/html_node/Invoking-guix-size.html

If the overhead is =E2=80=9Csmall=E2=80=9D, that=E2=80=99s fine; otherwise,=
 that may suggest
leaving it disabled in the default Mesa.

Ludo=E2=80=99.
