There's no need for Emacs to justify its behavior wrt
other editors or any other programs, to anyone. Emacs
users and developers can decide what Emacs behavior
should be, including default behavior.
Again: What's a good argument on its own merits,
without recourse to an argument from authority?
("Everybody else does it!")
Everyone in Texas might have 42 guns and attend
church twice every Sunday. That's not a reason
why everyone in Switzerland should act the same.

"Optimal" is perhaps in the eye of the beholder.
And it might not necessarily apply to _default_
And popularity outside Emacs does not "optimal"
make. You'll need a real argument, not just
popularity, as to why you think the behavior is
not "optimal" or, more appropriately, is not a

I don't think it has. Except that now we're
talking about "optimal" behavior and comparing
Emacs with other code editors.
Yes, those things diverge from the question of
what to use for the `frame-title-format' default.
I agree that that's an unproductive route.

Such a prompt is not a frame title. That's the
Unless, as I mentioned, it's a frame whose
selected window has a `*shell*' buffer, or
There is likely no single `frame-title-format'
that is "optimal" for all uses of a frame.
The question is about the default format.
I don't think that most Emacs frames, for most
users most of the time, are like CLI windows.

Minimal for distinguishing. And actually, I
suggested that we could reasonably include a
lot _more_ in the default frame title.

Yes, it can change when the editing context
changes, including the set of buffers you're
using. Whether that's a feature or a problem
is arguable. IMO, it's good, not bad, default

Fortunately, you can easily change
`frame-title-format' to fit your preferences.
As can I.

See above. You're repeating, out of order,
what you said earlier.
Whether the confusion you point to is generally
(i.e., for default behavior) worth the benefit
of not repeating the same long dirs in multiple
frames (which is the much more typical case -
see my previous mail), is an open question.
Clearly we disagree about the answer.

Same point. See above.
