Essentially, because there's no particular reason to ever use multiple slashes like this. While we could work to support it (and it would be extra work, since we're using a whole new system), making sure our URLs use the 'normal' format is likely a better long-term solution. If we make more thumbnailer changes in the future, we don't want to keep carrying special cases along with it.

That being said - I'm not ruling it out as a solution.
