I notice a big difference between the "old" and "new" functions
createDispatchEvent and fireEvent. The former checks for
hasEventListeners() while the latter does not. Is this by intention or
error of omission? It certainly seems unnecessary for every caller to have
to check for hasEventListeners() themselves, doesn't it?

"There is nothing more difficult to plan, more doubtful of success, nor more
dangerous to manage than the creation of a new system. For the initiator has
the enmity of all who would profit by the preservation of the old system and
merely lukewarm defenders in those who would gain by the new one."
