> It’s a larger mental leap to have to leave the keyboard.
I find this interesting! I've never considered myself "leaving the keyboard" on the phone as if I were task switching. When I'm done typing I flow directly to the send button and let the keyboard go. The fact that the button is above the keyboard makes no difference to me as long as it stays accessible.
Mobile keyboards also do have the advantage that they can at least change the label of the button; so writing Submit on the Enter key if it submits.
