When I'm receiving flight following from Denver Approach I am always told to
contact the Class D tower (Jeffco, Centennial, Front Range) before entering
their airspace.

Right. And they cut you loose in time to do so.

RFD didn't cut Mary loose until we were inside JVL's Class D --
something they had never done before.

We're smarter now, and cut THEM loose.
