Exactly the opposite of MC-164692. I do not know why that was "fixed", it was not a bug.
Entering a boat or minecart has nothing to do with a hand or an arm. I have entered multiple real-life boats in my life without needing to use my arms at all.
When you mount a horse, it now even looks like you're punching it.

Hm, didn't notice that MC-164692 was only about boats in specific. I'm reopening this ticket, but expect it to be closed as WAI or Invalid.
As you already noted, since MC-164692 has been marked as "Fixed", this behaviour is confirmed to be working as intended.
