1) You'll have to change it anyway if you want to support extensions.  
I haven't seen a discussion of this yet.

2) Introducing new syntactic constructs requires people to write new  
parsers for them, which can also introduce errors.

I'm surprised that implementers hadn't already found the problems I  
pointed out; that suggests there may be other issues that they haven't  
seen. Reusing an existing syntax that's widely used avoids syntactic  
problems, leaving the WG to concentrate on the semantics which are in  
their domain of expertise.
