Seems like a useful change and I can see how issues could arise if strings were stored somewhere after being upper/lower cased and then reused in a different locale. 

Is it correct to say that the assumption is these strings are all supposed to be US ASCII (eg protocol defined identifiers, or hostnames etc) rather than user generated text strings? That seems to be the case as far as I can see.
