I'm not talking about functionality under the hood, I'm bad-mouthing the
user-friendliness.
I used to be an ed user for a decade (I've coded on a game that offered only
a line-based interface), but that was Beattie ed which was _massively_ more
comfortable to use interactively than GNU ed (and probably way less
powerful). It was enough to bother with file transfers only for big edits.
But that was a special case. Today, even on a bad serial link, all you need
is a visual editor that does _not_ obey termcap/terminfo. In my experience,
the 99% cause of breakage is:
* weird ancient Unices: bad termcappage
* Linux/BSD: wrong terminal size ("setterm --resize")
(ignoring termcap works because last non-vt100ish terminals were made ~40
years ago)
Thus, I can't think of a scenario where ed would be preferred over a visual
editor. If such scenario exists, it's too obscure for the default small
system.
