I don't think so. ATM, there's plenty of high-quality reference code...
especially with Lars's tutorial. This is a different issue.

Not quite (though that would be a Good Thing).

More like a standard that says something like......

FOR SYNTH HOSTS:
----------------

If you follow these guidelines, you may call yourself an "LV2 Synth Host"
and you will be able to work cleanly with every synth that calls itself an
"LV2 Synth Plugin."

+ Support (at least) extensions A, B, and C.
+ The synths will have several MIDI input ports (for note data)
and several audio output ports.
+ All configuration will be done with the events extension.
+ All feedback will be done with the events extension.
+ The plugins may provide a GUI interface. Its width will be
200, 400, 600, or 800 pixels. Its height will be a multiple
of 100 pixels.

FOR SYNTH PLUGINS:
------------------

If you follow these guidelines, you may call yourself an "LV2 Synth
Plugin" and you will be able to work cleanly with every host that calls
itself an "LV2 Synth Host."

+ Freely use extensions A, B, and C. If you use any extra
LV2 extensions, try to make them optional. Otherwise,
please simply call yourself an "LV2 Plugin," because you
won't work with every LV2 Synth Host.
+ Provide several MIDI in-ports for note data, and several
audio out-ports.
+ All configuration will be done with the events extension.
(This does not prohibit you from also doing the same over MIDI)
+ All feedback will be done with the events extension.
+ You are encouraged to create a GUI for your plugin. Its
width shall be 200, 400, 600, or 800 pixels. Its height
shall be a multiple of 100 pixels.

Would somthing like this be *so* bad? There's still room for innovation.
There's still room for plugin authors and host authors to get together and
say, "We all want to start supporting extension D." And that would still
be cool because all the old plugins will still work.
