I don't see how you can possibly do that.  What is the definition of a
"feature"?  Concretely: If you decide that your implementation should
provide hash tables in a different form from the (optional) standard hash
table module, who's to tell you no?  You just claim that *your* hashtables
are a different feature from standard hash tables, and presumably they do
have some different sub-features or you'd just implement the standard.
Standards don't apply to implementations that don't claim conformance
to them.

The most we can ask for is that if an implementation provides a module
under a standard name, it provides the standard module, and not some
slightly or hugely different module.  And that applies to both WG1 and
WG2 Scheme.
