I think it was more Fandom wanted to upgrade but the highly customized Legacy Platform was too interwoven and having underling problems- so a Platform change was required.

Meaning the loss of many highly customized features we were accustomed to. And I think their hope is making up for lost customizations with new ones that couldn't be done on Legacy in phase 2.

But until all the bugs are fixed and we start getting these new customizations and perks we only can see what we lost or changes we don't like.
