I had some trouble locating these discussions on the oe-core list. Do
you have hint/link towards those discussions? I'd be interested to
read them and see what ideas has been discussed.

Has there been any proposals earlier?

Sorry, no real ideas at the moment. The main alterniatives, I guess,
are to conditionally add depends and configure options based on
either:
* More variables. Although this could lead to _a lot more_ variables
in the end. (I.e. see the recent discussion on the oe-core list on
task-base etc.)
*  On if certain other recipes are selected. I'm not sure that this is
even possible? (I haven't looked that much into bitbake and recipe
parsing) This is solution is obviously a lot easier when using e.g.
Kconfig-based configurations, like Buildroot.

I'm not sure of which option is the best, or if there is another
better option...
