Need help on Unused Declaration inspection management

I've been using this as one the most usefull inspection for many years.
But since Maia, I get many more method highlighted as Unused.

Particularly for API type project where top interface method are never
in use within the project of course. And also most Struts1/2 Action
methods get highlighted.

I remember playing with the notion of EntryPoint (was useful to
indicate Hibernate Entities getters/setters that were not hard linked
as used.)

Could someone point me toward some documentation on this please?

I don't to end up having to add a @SuppressWarning to all Struts and
API top level methods, that would kill the UnusedDeclaration inspection.

Best,
