I have no idea why you might think I'm trying to avoid that. 
I've just spent the last 8 years _not_ avoiding that - indeed providing exactly what you describe.
Turns out that SDP is a _really_ bad API surface for doing that. 
It is _much_ easier to get the SDP your enterprise devices are expecting if you start with a sensible
object model and mange that. So much so that we take the SDP the browser emits, parse it to an object
model and then go from there.

Why? Well because there is no pre-existing device on the planet, enterprise or not, that will consume the SDP
that chrome and firefox generate, so inevitably you need to rewrite it (and proxy the media, but that is a separate story).

Been there, done that, got the t-shirt.
