> I can't relate to this to be honest, I feel confident on my phone that main features are either right in front of me via a tap and less common features are behind a visible menu icon. Think how much worse it would be if double tap and long tap were required for common workflows. Some apps do require gestures but they either onboard you or the gestures are optional.

Not my experience at all. Snapchat famously made their UI deliberately undiscoverable so that only people who made an effort would find all their features; I don't know if Instagram deliberately copied that or not but a whole lot of its functionality requires blindly tapping somewhere that's not obvious to tap or dragging somewhere that's not obvious to drag (e.g. going backward or forward in a story, messaging someone).

My favourite example is pasting a phone number into the dialer on Android: you have to long press on the blank white input, and it will only even show the context menu if you've got a phone number on the clipboard already. A couple of versions back it was worse: you had to long press in the correct half of the featureless white rectangle, otherwise it would just silently not work.
