It's still the case on a Series X. There are separate pools for applications and games, as well, and the Series X is able to keep state for multiple running games at once, which is nice. The only downside is that it seems to cause a certain amount of pain with applications sometimes not working when there's a contest over sending Dolby to a receiver. On the time thing: turns out that PlayStation 3 and 4 will stop letting you run games if you replace the battery and it can't re-sync time with the PSN.
