Right, it's a trade-off.  All choices of default
behavior are trade-offs.

The question is: Which specific info is most
important to show in the frame title, for most users,
most of the time?

In general, I think that the info in the `mode-line'
is also good for the frame title.

Not that we would necessarily show all such info,
or show it in the same way (e.g. same left-to-right
order).  But such info is generally important and
serves to identify what the frame is about (the
current state of its content).
