Aaarrrrrggghhh :-)

Not a problem. AFAIK, the hints do not describe the v->f mapping,
but rather the one between the widget and v. It's plain linear in
this case.

I'd love a plugin host with a degree...

A well-designed set of tags like the ones you show above would
probably solve 99.9% of all cases. But you can't expect anyone
to dream that up in a day. Which leads me to my main gripe with
LV2: it was defined much too fast. In a normal RFC process, you
present the problem, give interested parties at least a month
to consider it and write something that exceeds the quality of
a whim, and then take at least as much time to study the results
and comment on them before anything is decided.
