I'm so used to gestures I can barely use a phone with button navigation. When I have to help my parents/grandparents with their smartphones I take longer just because they use buttons lol.
Also the 3 button navigation is not gone afaik. All OEMs I've used have it buried in the settings somewhere.

It's ridiculous how a well standing dev can just have an app removed with no warning or human investigation.
