Each space had separate operators, duplicating logic.
Use RNA properties instead so adding the ability to toggle other

extra operator per space type.
It's also nicer to show a check-box for something which can be toggled.
BF-admins agree to remove header information that isn't useful,
to reduce noise.

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
