Mostly I am.

When I'm forced to I do.

No, as a matter of fact EMACS wants a "meta" key.
On terminals lacking a suitable "meta" key, ESC is often substituted.

This use of ESC never was essential, it's just a kludge that should
have been avoided in the first place.  (TECO was the first and worst
offender, but at least it predated X3.64 so it had an excuse.)

That's not exactly what it says.  It does require that escape sequences
be properly handled, and in many environments that can't be reliably
done if you let users bang away on a separate ESC key.

Note that I suggested a second alternative if you don't like the one
about removing the ESC key.
