No.  GUI frames don't really have names, they have titles.  Only TTY
frames have real names, those Fn strings.  A name of a frame cannot
change, otherwise it's not useful for specifying the frame.

What would that be useful for?

In any case, you can supply a name for a frame using set-frame-name,
if you don't like the Fn notation.

It's an illusion created by that function.  That function is
mainly/only useful for TTY frames, because you have no other
convenient way of selecting a specific frame quickly: you only see one
frame, the current one, and have no idea what buffer is displayed on
others.  That's why that function was written; but in order to make it
work with any kind of frames, it was extended to GUI frames, although
it has no real utility in that case.
