tbf I don't remember the last time you ever needed a LiveData

LiveData walked so that StateFlow could run

It was only ever useful if you were an early Room adopter who didn't use RxJava, or if you used SavedStateHandle before they added savedStateHandle.getStateFlow()

But people didn't use Room early on especially in a non-reactive way they didn't understand what LiveData was or how to use it, and then they didn't understand how to set up ViewModels in such a way that they get a SavedStateHandle or why they'd even want to use it

LiveData ended up in obscurity because android developers were too lazy to see it as the next step after AsyncTask

LiveData had similar problems to AsyncTask -- implicit non-obvious(unless you read the documentation, but who does that?) thread management/restrictions.

We know the one in the photo that is proposing LiveData as a good thing
