I am not sure if these two maps are necessarily detached. When I want to
move a few subtrees, it might be natural for me to assume that I can
also move between them without having to invoke C-x @ ... again.

That makes sense, I just found out about outline-minor-mode-cycle and it
probably does make these keys superfluous for most uses. Removing these
keys seems to also open up a lot of key bindings that would otherwise
maybe annoy users if they are bound in transient maps (especially C-a,
C-e, C-k, C-s, C-c).
