Yep, the term was known when I became KN6DGW in 1953, but somehow no one

During 50 years in broadcast engineering I have never seen a resonant
broadcast AM antenna. Only reason for operating an antenna near or at
resonance is that’s where the feedpoint impedance is at its lowest value so its
easier to match.

Right, SWR (or VSWR = same thing) has nothing to do with the antenna
itself - it is all related to the feedline.
It does have a lot to do with the ability to match the feedline to the
transceiver which normally likes a 50 ohm load or something close - but
then an ATU can take care of that
Actually most are open wire feeders and have no networks.

Glue a Swiss Army Knife to the side and you have all of that and more.
