If you have a level 60 job while stuck behind ARR content, you have much more to worry about than your job quests. Regardless, this is nothing but a good change that I hope to see in the future from now on. And keep in mind, there are certain job quests in the 50-60 SAM/RDM quests (Samurai especially) that require you to head to expansion-only areas, so obviously you can't complete them until you reach said areas.
