I'm not sure.  What about

extern int f2();
struct NoExcept {};
template<typename T>
void f1() {
  try { f2(); } catch (...) { }
}
template<>
void f1<NoExcept>() {
  f2();
}
template f1<NoExcept>();

?  EH code could be disabled by some tags and specialization.  Especially
for a library that has a non-exception variant that would sound useful.
