Hmmm, what do we do to help Scheme implementations like PLT whose
front-end script *needs* to set internally used environment variables
like PLTHOME or PLTCOLLECTS?  This is unlikely to interfere with the
script, but it sure breaks the guarantee you're suggesting.

I'm searching for some wording in the
SRFI 22, and haven't come up with anything that fits yet.
