Exactly my point; environ is useful for debugging.  For that purpose
it doesn't need to be precisely specified or mandated.  For debugging,
it would be just as useful if (environ) printed out the environment
table rather than returning a Scheme structure [and more convenient to
type than (for-each (lambda (pr) (write pr) (newline)) (getenv))].
Consider the "room" function of Common-Lisp:
