Seems like a possibility.  Some questions:

It there a real techincal reason for this? What kind of tasks become
easier with this addition?

The return value from XML::Parser's Final handler is used as the
return value from the parse method.  Do you want your 'eof' to have a
similar effect?

Should the default handler be invoked for the 'init' and 'eof' events?
Will that break older code?

If you feed new stuff to the parser after 'eof', do you want 'init' to
be called again.
