I don't see where Ken's reply (as quoted) suggests anything like that.

What he wrote is that, formally, 10646 supports a mechanism to switch to
ISO 2022.

Therefore, formally, there's an "escape hatch" built in.

If and when such should be needed, in a few hundred years, it'll be there.
Until then, I find further speculation rather pointless and would love
if it moved off this list (until such time).
