After T272770: Error while usurping an account I decided to write some scripts to find hook handlers that actually don't have a runner. I found AbortMove hook which is actively being used in four different extensions actually was removed in 1.25 (why this is in "Bug fixes" section?)
Its usages need to move to another hook.
I think the handlers can all just be removed actually. I split the AbortMove hook into two different hooks, the MovePageIsValidMove and MovePageCheckPermissions hooks.
Out of the extensions in codesearch:
fwiw, we didn't have a real deprecation policy until 1.29.

@Ladsgroup With all these patches merged, can this task be closed? Or am I missing something?
It seems it's still used in some places https://codesearch.wmcloud.org/search/?q=AbortMove&i=nope&files=&excludeFiles=&repos=
I guess we can close it once they are cleaned.
