If fallback mode is defined and trans_id_enabled is set to false, the
session will be propagated using url() and purl() - they will add
SID if no session cookies are installed.  The only thing that is
missing is the first redirect which is used in session3 to determine
if the session cookies are used.
The reason it is missing coming from my opinion that this redirect is not
needed at all - if the cookies are used, SID will disappear from urls
automatically after the second click, but we'll save a reload. If
there is no cookies, url() and purl() will do the job. Of course, we'll
have SID in links at the first click, but it's only aesthetics. Moreover,
this behavior (the first redirect) is not supported by native PHP4 session
module, and even if we try to be compatible with the good old PHPlib, we
can not ignore changes. I guess the better way is to use the standard
trans-sid feature.
Nevertheless, it is only my opinion, and such a thing can be easily implemented
to accomplish the compatibility.

BTW, there are some more serious incompatibilities. Look in README for
them.
