Only for plugins, not the UI.
Do you know a host which passes the samplerate to the UIs?
(I do it in Carla, but I think I might be doing it the wrong way...)

Seems like a workaround for something that is rather important.
We want separation of DSP and UI objects, so the UI needs to know the 
sample rate.
Using an output port means waiting for the value, delaying full UI creation.
