If error handlers may only have static members, that means that
any data the error handler is accessing must have "global" lifetime.
If you wish to pass e.g. an ostream& to log the problem, you can
only do so in a global variable.

Not nice from a software engineering point of view.

However, the question is how much uglier the code gets with
stateful error handler objects.
