I forgott to type in previous mail:

In general, (I think) that allow to support commands that are available in
selected-window, to be executed in other-window, but does not have access to
commands defined in other-window, and naturally we can't executed commands from
selected-window if they are not supported in other-window. With other words, if
set of commands from selected window is S and set of commands in other-window is
O, than this will work in on the intersect of those commands, S∩O. Perhaps there
is more to it, but I think that is the minimal requirement (the commands has to
work on both buffers).

Potentially it can also result in many bug repports and /r/Emacs threads where
people wonder why it does not work some command Foo in other buffer.
