Probably pretty much forever, or at least as long as the language can
reasonably be called "C".  Removing C's existing for loop is just not a
possibility.  I was talking only about the possibility of adding a more
restricted loop construct.  C++'s range-based for statement might be an
inspiration (of course C still fully supports the existing for statement
it inherited from C).

I disagree.  The flexibility of C's existing for loop is an advantage.
