I hope you'll bear with me for continuing with this, but as I see it, if LV2
is supposed to become the defacto plugin standard on linux for the future,
and ardour wishes to support it, I don't see how this can not become a
greater issue as time goes on.

parameter per se, but to the ardour GUI element? Is this correct?

If this is the case, would a possible workaround to the external GUI problem
be to include a parameter slider or similar representative GUI element on
the automation track itself. In this way, automation and midi binding could
be managed from the same place for individual parameters without the need to
load the main plugin GUI at all.

I know this is quite a significant design change; just throwing ideas out to
what, as I said, could become a sticking point for future ardour use under
