I've noticed that --zap tends to leave a lot of traces still. Is it application specific?

I'll give an example:

If I run brew uninstall --zap vmware-fusion and then brew install vmware-fusion VMware Fusion can still pick up various bits from its previous installation (like how my 30-day free trial has expired).

If I drag VMware Fusion into AppCleaner, then run brew uninstall --zap vmware-fusion, then run AppCleaner, when I reinstall VMware Fusion, I can restart the 30-day free trial all over again.

I know this because I have been doing this on an as needed basis for like 5 years now ;).
