But if a server implements "bis", it MUST also support lots of other 
unrelated features. This is a question of granularity, and optimally, we 
won't need "bis" at all because all the things we add can be discovered 
individually (such as support for DAV:lockroot, for example).

We have implemented it but found we're not using it in our own client 
for the reasons given above. So the new revised proposal isn't based on 
theory, it's based on running code. This is the approach we find is 
working, and we've been using it since 2002 when we initially proposed it.
