    Obviously we need to distinguish between "switch-to-buffer the command"
    and "switch-to-buffer" the function.  I don't care about the behavior
    of the command, but of the function.

They are the same.  We could make it do something different,
then specially restore the old behavior for interactive calls only.
But I think it would be a change for the worse to do this.

    And the problem is made worse because there is currently no function that
    does what we want in such case, i.e. "show buffer B, preferably in the
    current window".

Perhaps the right thing is to define a new function which does that.
It could be called select-buffer, or switch-to-buffer-somewhere.
It could leave you with that buffer visible in the selected window,
which would be the previously current buffer if that is possible.
