Ok, that's a good reason, but it would deserve a comment in the package
definition to explain matters to future readers.

It would be useful to explain in the description that the output
that needs to be installed, depends on what other software in in the
profile.  E.g.:

"Fcitx5-gtk provides a Glib-based D-bus client and IM module for
GTK+2/GTK+3/GTK4 applications.  The output that needs to be installed,
depends on which variant of GTK that applications use.  When in doubt,
it is sufficient to simply install all outputs."

Greetings,
Maxime.
