Someone at wotc seems to have spent a lot of years trying to remain unexposed to it, I wanted to be sure that there was a chance for them to be mentally prepared to burst that bubble

The trouble is that "a second map" is bonkers unreasonable and more capable vtt's will always be capable of trivially displaying it. Once the bar between seeing it & not seeing it is a clash between "plsyer:can you scroll out so I can see?" vrs "gm:no I
won't" any consequences of imperfect information stemming from that refusal to scroll out for Bob's gods eye view can quickly crash into a fraying social contract.
