User blog comment:Rupert Giles/Prototype for a new article layout/@comment-8459116-20150215180326/@comment-1038387-20150215181028

This is just a prototype. The entire point of prototypes is figuring out mistakes. There are plenty. This is nowhere near a final version, and was never intended to be anywhere near a final version.

The templates and features won't be "unusable". Templates have issues - tables can become dislodged, templates using absolute width can cause overlap with the RWA box and tabbers can create large white spaces. Features aren't affected yet because the prototype only exists for the mainspace, not for wiki features.

Those are all things that will have to be taken into account as the prototype is being worked on. It can't be withdrawn, because it's not implemented yet. Except on those two wikis, and there only partially.
