I've been thinking of it too, but:
a) I wanted ensure that the prefetch will be disabled
b) that variable is used basically only here (and in initDNSPrefetch(), where
it's set to 'false' again) and after this change is means "explicitly
disabled by settings" here, from my point of view.
I added some debug prints around and the initDNSPrefetch() is called plenty of times after each page reload (or load of a new page in case of Evolution), thus the value is reset often.
