Transiting E (VFR) at Avalon some time ago, I was asked for a position report by 'the tower". I replied "over the saltworks heading to point Richards". Tower then asked for a bearing and distance from the reference point because "our radar doesn't have maps". I was slightly surprised.
Perhaps its time you - and a few others here - visited an ATSC.
ATC air situation displays and Tower TSADs don't have a geo/topo base map such as VTC or ERC. To reduce clutter they have a base "mud map", with published VFR and IFR points and routes etc. relevant to the operating position. Aviation maps available on overhead displays or the console. Ditto for ATC around the world.
So obscure places not marked on aviation charts such as you gave are unlikely to be known by ATC nor - importantly - other aircraft listening who may be traffic.
But I suspect you well knew that
and sadly would have left a great impression of GA pilots with ATC and listeners.
