I'm ready to bet that the 8.0 job shake up we'll see is going to be 100% focused on tactile feeling and class customization between different rotational sequence types. They're not going to suddenly change their current direction because that's what their current audience wants. They may have done it in the past when it came to their older audience but back then they had the benefit of still riding the wave if their game's success so it probably felt ok to butcher everything and bring up their new direction that started in SB for encounters and in ShB for job systems that's stayed since then.

That and older content would get in the way of major reworks anyway.
