Even if they wanted to try something like that, it many cases it'd probably require a fair bit of code-restructuring so ideas aren't tried willy-nilly. PostgreSQL is great in that they've put serious engineering effort into things like SQL standard,reliability,etc , but one thing that's frankly quite horrid in 2025 is that their reliance on a fork-model for processing has left them with many _important global variables_ that needs a fair bit of refactoring to take out (the fork-model does give some stability perks since the code is written in C, so it's not an entirely horrible choice).
