Sorry there was an unfinished sentence above:

The Royale bindings implementation does not run

was supposed to be
The Royale bindings implementation does not run in exactly the same way as
Flex, and this remains true after the changes. So legacy code that depends
on the order of execution of Flex bindings probably won't magically start
working with this. But it at least means that all the bindings from the
original code should be possible to run.
