The standard is as it is, nothing can change that at this point.
As long as you don't break any code that conforms with the standard,
you have wide latitude to do as you wish. As it says in CLHS 188.8.131.52:
...it is implementation-dependent whether the lexical environment
in which the initial value forms (variously called the form1,
form2, form3, step-fun, vector, hash-table, and package) in any
for-as-subclause, except for-as-equals-then, are evaluated includes
only the loop variables preceding that form or includes more or all
of the loop variables;
Conforming programs will never depend on any particular choice that
the implementor made here. But beware:
[The] form1 and form2 in a for-as-equals-then form includes the
lexical environment of all the loop variables.
Conforming programs *may* depend on this latter clause, so don't break that.
