Comment (by jjstickel@…):

 Replying to [comment:1 mojca@…]:
 > May I suggest using `wxwidgets` as the variant name rather than `wx`?
 >
 > In case that support for version 2.8 is needed we could have both
 `wxgtk28` and `wxwidgets30`, but if it's feasible to fix the problems, it
 might be easier to fix the problems than to keep the wxWidgets' legacy
 around.

 Sure, wxwidgets can be used for the variant name. At this point, my
 thought is to just leave it commented out. If there are no bug reports or
 complaints, I would like to remove the wxwidgets variant entirely at some
 point in the future.
