FWIW, IME it is quite frequent to want to see where is the buffer
position whose value I just saw as the result of evaluation.  This is
important when debugging code that computes those positions
incorrectly.  The (very inconvenient) alternative is to have another
Emacs session with the relevant buffer displayed, where I can try
these positions.

The problem I have with popping a new window or frame is that when you
resume stepping through the program, Emacs removes them from display,
at least by default.
