Looking at that post, I think that it might still trigger on the current patch. It'll be a future patch when they disable it.
You can still go ahead now if you wanted. If you fail the quest now because of the bug, you'll at least get to retry the TLSQ again whenever the new version gets triggered.
They did something similar a while back with the OWLs quest, where they took down the original version to fix a bug and then retriggered a new version at a later date.
