Yes - renaming (either on import, export, or both) supports this kind
of wrapping. The only question is whether the exported name can be
imported elsewhere without further renaming.

Yes, as above. However, no SRFI-83 library would be able to import the
names without prefixing them or renaming, since every SRFI-83 library
imports "scheme://r6rs".

If we manage to at least agree on libraries that are all in the
"scheme://r6rs" (e.g., this SRFI), then we may eventually be able to
agree on ways to portably define new languages --- where a new language
could provide alternate bindings for names exported by "scheme://r6rs".
This SRFI, meanwhile, doesn't support it.
