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.
