I disagree wholeheartedly - the inclusion of Arabic is a logical next step.
If its not needed (due to wanting to save memory footprint or the interest
is not there), then compile it out by default and include it via command-line
configure options and ifdefs.  The reason I say this, is simple.  Any
application that will include fribidi will have to include some shaping code
in order for that application to be Arabic-friendly; so the two, from an
Arabic prospective, go hand-in-hand.  Certainly if there are other shaping
issues related to other languages (like Hebrew, which I believe there are
some), as far as I'm concerned, those should be added as well with the
appropriate flags.

The other argument that could be put forth is that fribidi's inclusion is
difficult enough in most applications (try convincing a application author
of its inclusion and he/she will go into a rant about it only catering to a
very small minority of users and not worth the headache).  To have those
authors also consider a second library would create more problems than it
would solve when it comes to getting it adopted.
