Does it disable the optimizations always, or only when there is
right-to-left text?

Yes, that matches the little I remember.
If the optimizations are disabled only when there is right-to-left text,
and if the users of emacs-bidi think it is better than nothing, we may
as well include the feature anyway.
If the change requires disabling optimizations always, even for people
who don't use right-to-left text, that is potentially a serious
problem. Maybe it can be solved by adding a flag that people must set
in order to use right-to-left text. Of course, an automatic solution
would be better, but the flag would be enough to make it acceptable.
