Comment (by dd32):

 Reviewing PR925, it took me quite some time to figure out exactly why it's
 wanted/required/needed.

 Philosophically I feel that `upgrader_pre_install` and
 `upgrader_post_install` should've covered these, however the latter is
 only run on a successful call to `install_package()`, and that's written
 into a lot of existing code, so changing it's behaviour isn't really
 possible.

 Adding a filter, potentially marked as temporary for a feature plugin,
 makes sense to me, but I'd probably just call it
 `upgrader_install_package_result` instead.
