The sysutils/baloo-widgets port has the DOCS option explicitly stated in its OPTIONS_DEFINE. However, it does not utilize the option at all. The file contents of the packages with or without the option enabled are identical. The option should ideally be removed.
That option is required by the tooling from kde.mk, as ports with CATEGORIES=kde-applications "generally" install documentation, that has been moved there.
But as you noted, there are some exceptions that now have "empty" documentation options.
If that is the case, should I bother submitting any other bugs about other KDE-related ports that are also like this one, that have DOCS option but no actual docs?
I think it would make sense to gather them in to as single PR, like have a list of them.
Then, we have an overview and can decide what to do
* nothing (too few to matter)
* something, like making adding PORTDOCS controllable
* something, like moving DOCS handling completely bakc to ports
it mostly depends on the amount of ports :D
