I think it is better to check for the existense of these vars,
not the version!

Right :)

This can be done by a register_shutdown_function() who registers
all the vars in $_SESSION, using session_register. That's all :))
If I can understand this new feature correctly (I never used it).

I think Rasmus referred to the register_globals deprecation
question, which is another thing IMHO, that need to be documented.

There are many "user notes" coming up about using:

extract($_REQUEST);

and the like to simluate register_globals. This can
be a really bad thing sometimes...
