Except that this one does on the front page too, so it's not like 'front.template' has no full stop and 'submission.template' does.
Similarly in 'threads' some comments do and others don't. 'tis mildly curious.

If I were to hazard a guess -- it looks like a templating bug. Some template has a period in it.
