I don't think it's a big deal, just a slight inconsistency. I just like and appreciate clean URLs, and for me that includes a nice end, which can be a file extension for a file, or a slash for a directory or resource. I'd probably suggest we undertake a bit of cleanup some day, but we don't have to change any others in this PR. 

However, the old URLs being removed do indeed have the trailing slash (you can go test on the site). The `page` helper adds it for you. I think we should keep them.
