exactly. But in order to have a discussion on this, we need to hear from the 
proponents of those use cases what functionality they are missing in QUICv1.

But requirements are not about the "how" - that was exactly Lucas' point. 
Requirements are about "what". So statements along the lines of "my use case 
requires the ability to fail over a connection to a different path", etc. would 
be informative. Saying "my use case requires draft-deconinck" less so (for 
example).

I'd hope not? Because if there is a long shopping list of requirements for new 
QUIC functionality to support a particular use case, that'd look to some as a 
pretty convincing case that maybe QUIC isn't really a suitable starting 
technology.

Thanks,
Lars
