Yeah, the question is basically which entry pages you want to support. I think it’s nice to be able to link to a particular file on the master branch and have it load instantly, too. Loading older verisions, on the other hand, has its uses but is less important.

For a repo with thousands of files, it might make sense to limit entry pages to only directories and .md files (and other prose files), which are more likely to be linked to. You can also skip shipping a Markdown renderer this way!
