The usual use case is: Somebody -- either admin or some command 
implicitely -- executes modprobe aes because some text file
specifies the aes cipher. At least on my system that loads
the C version when both are enabled. modprobe will not load
multiple modules in this case.

I don't think modprobe knows anything about these priorities.

But that would require teaching the module loading user space
about all this first, right?

Also if one implementation is always better than the other
then I see little reason to ever have both.
