I’ve been using android since 2010, and it’s gotten significantly better over the years. There’s only a few things it doesn’t back up, like text messages and app data, most of which you don’t need.

It is not Android that is backing up most things though, it is mostly done by Google Services. That means that your data is effectively vendor locked-in if you want to use Android as an actual open source project. Google gutting the AOSP to this extent should be illegal (maybe even is, but might is right).
