I'm all for it.

Easy, I can do this. Extensions would probably break, though.

Doesn't matter that much, see below.

Easy: Just change the default in shortMD5 from 10 to 32, all places  
should work. The remaining ones should be easy to find. Again,  
extension could break or at least still use short hashes.

Second possibility: Make shortMD5 always return full md5 hash,  
ignoring the requested length. *Will* break some things. :)
