Thank you for the contribution and your interest. Since we'll have to maintain this, we first need to prioritize it. @ronniegeraghty could you have a look? We should talk with the service team.

We are also a generation-first Azure SDK language, which means we generate as much as possible. For Service Bus that might be little to nothing - as with Event Hubs - but @LarryOsterman would be best to advise if we're ready to accept work currently.

I recommend holding off until we prioritize maintenance of a Service Bus crate. In general, I highly recommend opening issues first so we can prioritize accordingly.
