Agreed, the idea is to eventually delegate mapping it to the host.
I must confess that I'm guilty of that, too -- my faust-lv2 and faust-vst plugin architectures for the Faust programming language all do their own midi cc processing (according to the corresponding hints in the Faust program), even though in this case all the control values are also exposed as control ports (and the two work in concert, of course).
In principle most of this could (and should) all be done on the host side (although there might be special circumstances under which some processing needs to be done on the plugin side). But right now you can't even be sure what facilities the host offers for that purpose. Does it support the midname spec? Does it take corresponding hints from the LV2 manifest? Or will it simply pass on midi cc's if there are midi input/output ports? Etc.

I admit that I'm confused by the state of affairs in this department, and I'm probably not the only one. Sounds like a great topic for discussion at next years' LAC. :)
