Yep you're probably right that a good sfv checker can check the release no matter when the sfv was upped. But believe it or not there are actually some lazy mofos out there who try to up a big ass thing as one big file which occasionally will xfer corrupted which is just a waste of time+bw. Ensuring that the upload is blocked until an sfv is in the dir first is a nice way of encouraging these ppl to xfer large files properly..by making a multipart archive and sfv.
