I'm not against the idea of this. The observation I made during the discussion is that uni streams are a critical part of a H3 session. Failure to read the uni stream type successfully will be a killer: reading a single byte is more resistant to failure.

I think we should put some energy into the H3 interop to try and ensure that implementations are resilient to varint stream type failures. I wonder if this can be done as a test vector, or by some other interop test design.
