My point is that email basically hasn't evolved meaningfully from the 80s and other than the main feature of sending text all of the functionality is locked between specific providers. Tags vs. folders vs. labels, chat without email, encryption, etc. Nothing other than the baseline functionality is standardized.

Nothing other than baseline functionality should be standardized. Client features are totally irrelevant to the goal of sending and receiving messages.
