The issue is that etc-update doesn't have the version of the config file
as installed by the version of the package that's being replaced, so it
can't tell the difference between non-trivial changes to the config file
as shipped by gentoo between the old version and the new version and
non-trivial local modifications that I've made myself to a config file
which has not been changed between package versions. I've definitely had
etc-update ask for confirmation on files I'm sure I didn't change
(including, in some cases, executables that get installed in protected
directories).

It's understood that there is a difference between what I'm using now and
what new package comes with. But there's no information on whether that
difference came from local modifications.
