Output CV port for lv2 plugin

[jpka-]

Hello.
How do i define output CV port with Faust using faust2lv2? As per https://faustdoc.grame.fr/workshops/2020-11-21-faust-vcvrack/ i am trying to add [CV:0] metadata to bargraph name, but no effect in generated .ttl file. Is [CV:0] metadata intended to work with faust2vcvrack only?
Thanks!

Edited: I mean i expect similar to this change at .ttl file:
From: a lv2:OutputPort ;
a lv2:AudioPort ;
To: a lv2:OutputPort, lv2:CVPort ;

VCVRack related metadata are not supported in LV2 architecture.
