I do think (more like hope) that the reason there are so many empty enclosures at the moment is due to the elephant shift, and that they plan to rejuvenate not just TOTE but a whole lot of other areas.
As in the Zoo is in a holding pattern waiting on their departure.
In possible good news too the elephants were not doing their training when I was there but two of them were actively engaging with the travel containers.
Manjai and Luk Chai were in an enclosure together as well and having a lot of great interactions.
