I've been specifically requested to add such support into IE by
various customers. Most of their use-cases involve script that is
trying to 'clean-up' event handlers for which they did not set, and
do not have a pre-existing handle to the function callback.
Could you be more specific about the use cases?
One use case that hasn't come up but may be better supported by other
means: debugging.
As far as I can see, there is no view in, say, Firebug that shows me an
overview of event listeners added with addEventListener(). In many cases
this would be very useful.
(By "better supported by other means" I meant that an alternative would
be to enable something like the proposed functionality in "debug mode"
or "debug builds" only. It seems more useful to me personally to simply
have it available though.)
Like Boris points out, there is no need to expose debugging APIs to web
pages. Browsers can expose those thorough internal APIs to their tools.
There is no API to enabling stepping through javascript or breaking on
all exceptions either.
