Also -- are you, like me, bored with LADSPA plugins crashing your host
in tedious, obvious ways?  How about an LV2 plugin that expects a
particular extension but doesn't really need it so marks it as
optional, then turns out not to have been tested without it -- and,
wouldn't you know, every host except yours happens to support that
extension?  Wouldn't you love to be the first host to run the untested
code path in production?

(I freely admit that this is a sort of FUD, but it happens to be a FUD
that is playing on my own mind at the moment.  Reassure me.)
