(Maybe it's just too late for me to grok this...)
So it's the plugin asking the host what it can expect ?
Isn't the LV2 way to do this via features (i.e. the plugin
checking which features the host provides) ?
A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
