I really would like to clean up several things on XY exit so an event for it would be really nice

Should reside in "Other Events"

And apart from the "Action = Script" it should probably have an entry for "Default" which means: Just do what is configured in "Configuration | General | Startup & Exit | Save Settings", in other words: A standard exit

You mean when "Action = Script" it should not do the default stuff?

I can see several possible actions:

None
Default
Default + Script
Script + Default
Script Only

Well, rather confusing... I would prefer something more simple.

It's an advanced feature, it can have advanced options

A few of the other cea entries have a plethora of options as well.

I could live with a if you don't want to invest much time in it, though...

I'd prefer the usual one: Understanding that:
None = Default
Run script = Default + Script

Ok

Unloading XY involves a lot of steps. It will take some time to find the best position where to insert this "on exit" event. I now decided to place it right before the automatic save settings on exit (if any). This is a position where theoretically the Unload process could still be aborted (XY stays open) and/or save settings could be skipped. This gives us some options for the future.
