Auto-update of native application bundles

A question for the JFX guys on JRE+JFX co-bundling:

Now that JFX is co-bundled in the JRE does that mean to upgrade to a newer
version of JFX we will need to upgrade our JDK/JRE each time, or do you
intend to have patch updates?

I guess ultimately my question is will the developer be able to mix and
match JRE and JFX versions or will it be a case of JREu6 is locked in to
have JFXb2.2, and if you want JFX2.3 then you have to upgrade to JREu7 (for
example, I'm just making up version numbers).
