Not quite. It auto-configures by looking for available libraries.
The Apple symlinks fake out the autoconfigure by making it think
that libreadline is present, when it really isn't.
If you remove the symlinks, the autoconfigure process will then
fall back to "builtin".

Not if you replace them with a "real" libreadline.

I suppose there are programs that make minimal use of libreadline,
calling only a small number of routines for which libedit does
have equivalents.  For those programs, it is sufficient to provide
a link to libedit.  But I would guess that those programs would be
equally happy to have a full-blown libreadline.
