Why not more?  We already show the buffer name in the
frame title.  That's more than just the host name.

That can be viewed as a plus, not a minus.  The frame
title tells you what you're currently doing/using.

And that's what we already do by default: the name
of the buffer of the selected frame is in the frame
title, by default, when you have more than one frame.

Right.  And?  A given frame would tell you which
remote host was used for the buffer in the selected
window, if that info's included in the frame title.
