The question raised was whether the apparent
non-update of the esc-map bindings was deliberate
or an oversight.

When you say "they" were bound ... and "they" were
updated at the same time, is it the same "they"?
Does "they" refer to the global and esc-map keys
for the update, as well as for the old bindings?

Are you saying that the esc-map bindings used to
be bound to (forward|backward)-*, and they were
"updated" (at the same time as the global-map
keys) to the same keys: (forward|backward)-*?
