User blog comment:MisterWoodhouse/Pausing UCP migrations to resolve some critical blockers/@comment-24688171-20200831140755/@comment-26939652-20200901133201

Ugh, please don't nit-pick about physical and perceived platform. What UCP is now, is what some wiki's have been migrated to.

It wrecked a number tools and functionality, missed critical functionality and is built upon a newer version of MediaWiki, whether that's a plus or not only time will tell. Some like the new editor, some don't, but they certainly miss feature parity. That's the perceived platform.

Honestly, I still don't understand why it was decided to go with the 2017 editor, when even Wikipedia hasn't. It is notably worse in performance, has severe UX mistakes and generally feels like someone's wet dream in scripting, without actually doing things that save editors time.

On top of it, UCP's performance is notably worse at the moment and that can be blamed on the physical platform.

More importantly, UCP is what Fandom decides it wants to be. It isn't possible to have things on UCP that interfere with MediaWiki upgrades. Another is no usable forum, no wikitext in comments, no chat that isn't based on a 3rd-party service with bad security and privacy practices.

Whether this will be possible in the future is very questionable.
