Busybox has gone more than a decade without having that, and nobody's
ever complained that I noticed. But they do have a separate ed
implementation because explicitly it's in posix.

Me, I use the "v/y/p" commands that are missing from busybox vi because
it's the cut and paste functionality. (I only know a dozen or so vim
commands. before that it was Joe, but joe and ctrl-s do not combine
portably, and wordstar bindings wanted ctrl-s...)

What does interactive line editing have to do with sed, a line-by-line
regex stream processor I previously wrote the busybox implementation of?

Just wondering.

"A bad thing exists".

Don't care?

Either it's "mere aggregation", or a license violation.  Pick one.
