I have yasnippet set to trigger on space, which makes the "the" snippet extremely annoying. I can't find anyway to prevent feature-mode snippets from being loaded. I think it would be best to at least allow me to opt out of using the snippets since I might have my own.
Incidentally, since the directory is not added to yas/root-directory, doing a yas/reload-all will mean they are not loaded which is how I work around this.
We probably can add a configurable var for that (which will default to true for compatibility).
