But what does it do if it's set to 'None'?  And even if it's happy with 
this, will the fifty or so other existing application frameworks be happy

Compatibility with the vast existing app framework code base demands that 
environ values *must* be strings, or else not present.  (Guess I should add 
that to the spec.)
