Right. More generally, this UI proposal (as most unsolicited ones are) is a snapshot of a single page. It doesn't aim for consistency across the other pages, or look at workflows involving more than one page.

"What happened to this file?" is one of the most common tasks I have, and it's poorly supported by every web VCS interface I've used, including GitHub. This proposal would make the situation even worse, by hiding any remnant of changes in the file listing.
