I think we should make it more stronger saying "There is one to one mapping between Subgroups and Streams"

That's generally true, except the special cases mentioned below (if a stream is reset prematurely, or other upstream conditions). Maybe we could say that it is a one-to-one mapping "under normal operating conditions."

I added "and are sent on a single stream whenever possible.", which I think conveys what we intend?

Wonder why we need to add the additional qualifier for WebTransport?

I get the intent here. But i feel its lacking the alternate case of when there can't be be 1-1 mapping. Some clarification text will helpful here
Clarify the case for multiple QUIC streams in the Subgroups intro. The current version reading "some cases" makes the use of multiple streams sound infrequent, and the relationship isn't made clear until a few paragraphs later.
