Left a couple comments regarding a possible longer term strategy, but this is looking good. Thank you for picking this up!

I think these changes are moving in the right direction, but I think this should be split up into multiple PRs.

@atlowChemi just a heads up if you come back to this PR - there will likely be new flags to account for from #54429. A lot of internal refactoring also happened, so the diff here should be a lot simpler.

@cjihrig Thanks for the heads up!

I am trying yo get back to this, been pretty busy in work & personal life lately, hoping to get back to this soon 🙏🏽

Other than docs, this looks pretty much done!

I have some issues with the tests

Do @RedYetiDev's comments make a difference? If they still fail with those changes, I can take a look.

They do! Thanks @RedYetiDev 🙂
I actually noticed it just after I wrote here seeking for help, but took some time to get to it..
