Having an separate branch has at least one merit.  As far as
it is branched from a fairly stable version, a person
working on the branch can be sure that any problem in that
branch is caused by his change.

For the case of bidi, if there's a plan of another big
change in the display engine, the above merit is big.  With
a separate branch, people working on bidi code don't have to
be annoyed by bugs of that another change.  Otherwise, I
think having bidi code in the trunk is better.

By the way, the case of emacs-unicode is very special.  It
simply can't be in the trunk while developing because the
new unicode feature can't be toggled.
