Uh...why would Sony (or Microsoft for that matter) go back to a split memory pool? Didn't they already see how horrible that was for devs with PS3 and how unified memory gave 360 and PS4 the advantage?
That Reddit stuff looks like someone who wants to throw together an exotic architecture but doesn't know how system architectures work.
Devs already have to deal with a split memory pool when doing PC ports. The split memory pool isn't as big of an issue when your memory pools are in the multi-gigabyte sizes. When you have a 10MB/32MB little buffer that must be managed on a per frame basis in the GPU, that sucks. When you have 8+ GB to play with, it's just maybe an inconvenience. The above rumor would make the PS5 basically look like a normal PC with 16GB RAM and a 8GB video card.
Although I think if you do see a split memory pool, it will more likely be split along OS/Game. I would say give 4GB LPDDR for OS, you don't really need anything more than that and you could make it very low power in standby mode, and 16GB of HBM for the games.
