I think you can test for nulity which is much cleaner and safer. Besides,
you're not supposed to break the API. So far, we mostly removed buggy stuff.

Yeah but clutter is clutter. And sooner or later cargo cult will ensure that
someone uses the function so it cannot be removed anymore. Better not add it
in the first place.

We don't have a serious plan on exposing Lua modules to the in-VLC Lua
interpreter, so this point is totally moot.

I totally disagree.

I think so, but that's irrelevant. A bad way is a bad way and we have spent
far too much effort removing polling. I am SO FED UP with this particular
topic coming back all the time.

You're reinventing history for your convenience.
I opposed merging the extensions in the first place.

It is. I have had to deal with cruft for longer than you.

Well, they're already removed then. Problem solved.
