I will indeed ignore most of what you say -- because you seem to
completely misunderstand what this discussion is about.  See below.

Using the minibuffer doesn't by itself cause any window to be
selected.  Using the minibuffer just supplies to whatever command that
prompted the user with the response to the prompt.  Then the
minibuffer is exited, and only then the command continues its
execution, and could very well choose another window to be the
selected one.

This discussion is about what happens _immediately_ after
read-from-minibuffer exits, which just provides the response to the
prompt.  It has nothing to do with what you are talking about, and
doesn't affect the window that will be the selected one after the
command exits.

read-from-minibuffer invokes recursive-editing cycle.  When that cycle
ends, it should leave the window/frame configuration intact, or as
intact as possible.  Why? because most commands that invoke
read-from-minibuffer in its interactive form do not expect the window
configuration to change after the interactive form finishes its job.

And if you still don't agree, then let's agree to disagree.
