I thought you wanted to avoid popping up a new frame.  At least in your
first mail you said "pop-to-buffer DTRT: it reuses the existing frame".

If you have `display-buffer-reuse-frames' set to nil, `pop-to-buffer'
will not reuse another frame displaying that buffer either.  Please tell
which specific detail of `switch-to-buffer-other-window' you dislike in
the present use case.  Note: It can't be the `other-window' argument,
because in that case we'd have to change the names of the respective
bookmark functions.
