Buddy, the point being made here is specifically Android 10. I just made a comment on your thread about this exact thing.

At one point in time there was a version of Android that introduced gestures and it broke third party launchers that have gesture options themselves. People were freaking out because they thought Google was going to make Android natively kill 3rd party launchers.

In truth it was a bug with gestures and 3rd party launchers. It had to do with the fact that gestures were new and that version of Androids gestures didn’t disable or have issues with 3rd party gestures interfering with one another.

I get your frustration a lot of people at the time understood your frustration and were worried but newer versions of Android no longer have this issue because the third party launchers can take advantage of the built in 1st party gestures and add their own additional gestures.

Also, Xiaomi is not exactly what I would call an LTS phone if you want longer service for support Pixel and Galaxy (especially Galaxy) are about as good as it gets on Android.
