I don't think so.  The functions are supplied to be extensible and
flexible.  It's hardly harder to use a function widget than a builtin
one and it's much easier to change it.  For something like this, which
runs external commands and handles the output, it's also much easier to
write the function in the shell command language than in C.

One of the reasons for the new manual roadmap is to indicate things like
the presence of add-on zle functions documented in zshcontrib which users
might otherwise not notice, although it doesn't specifically mention
edit-command-line.

Historical reasons, presumably, since this came from ksh.  It's not much
used.

Not that I'm aware of.  Set it to what you like.
