Unless consoles magically develop that amount of VRAM, it will be wasted. Developers, with rare exception, are going to target Series X and/or PS5 and a vast majority of people are still playing at 1080p. Outside of epeen measurement, it is functionally useless as it will spend a large majority of its life idle. By the time it may become useful this generation of card will be long in the tooth if not outright obsolete.
I'm not sure this is entirely true. I was checking dedicated video RAM usage while playing Horizon: Zero Dawn and it was up at over 10GB, so I think there will definitely be games that check how much is available and throw things into video RAM if there's space available to avoid the transfer from regular RAM/disk.
This could be a way for PCs to compete with Sony's claims to their SSD performance of the PS5 with all the dedicated decompression stuff going on to get things from the SSD into memory, while on PC you could just keep it in memory if you have enough.
