Yes, there's no compelling reason to hold up the handling of all files just because you need to get a response concerning some limited number of files--the system could queue them up while continuing to handle the rest. The response isn't going to abort the entire operation, and even if you explicitly abort using Ctl-C, the system won't undo what it's already done with the preceding files. It's pure short-sightedness (and laziness) on Microsoft's part.
