Looks Absolutely Fantastic To Me.

Please push directly to staging once Patchy has finished testing the compile
(about 30 minutes?)

I had tried this very approach a while ago, but there were some problems.
Unfortunately, I can't remember which problems I encountered.

One issue might be that all links to one particular snippet will be broken with
that patch.

If you don't encounter any problems with broken links etc., then I'm fine with
the patch.
