However, if there's not enough time to do everything requried, then I
believe that low-risk things like "remove the threads extension and the
threads subsystem" could be left to the user (provided that they are
documented).

I think we could ease the threads subsystem migration.

For most cases threads subsystem configuration is empty as it was just present

in our default config as <subsystem xmlns="urn:jboss:domain:threads:1.x"/>

We can change parser that in case that only empty config is present it wont

add the subsystem at all, this should ease the migration for users migrating default configurations.
