Indeed it does not.

As brought up on l-a-d by Stefano D'Angelo, it should be possible to
make backwards compatible CV ports by still using the type
lv2:ControlPort, but then providing some mechanism for the host to
indicate the port is, in fact, connected to an audio buffer.

Hosts that don't support this mechanism would just use it as a control
port, so such plugins will work fine in existing host (just without
audio rate controls).

I am working on a port of blop to LV2 that will use this to get rid of
the variants.  Report/examples soon.  In the mean time, just make your
ports lv2:ControlPort or lv2:AudioPort for testing.
