This is a good point. Would this have performance implications for down-level browsers? I don't know if prescanners etc in contemporary browsers are smart enough to ignore <script> tags that use a non-JS type attribute.
Gecko's is not. Not least because as far as I can tell scripts with unknown type are in fact always loaded, just not executed, and block the parser while they're loading, so you do in fact want to preload them! I'm not sure whether that behavior is Gecko-specific or not, but I suspect not: I recall people using unknown script types to do preloading in general.
