What a shame.

For dinkumware stl (for VC6.5) it is possible to write a more
specialized metafunction:
is_stl_iterator<> as the relevant iterators has a common base class
(vector<T> uses T*)

Is this also feasible for other stl-implementations?

Of course, this would only solve the problem for stl containers. The
question is whether this is a common enough usage that it is advisable
to implement support for it.
