Yeah, if you and your opponent want to play your next match as soon as possbile (even before the first deadline) you're definitely allowed to play it. Some people have some changing schedules and/or some other things to do in 2 weeks, so it would be good if they'd finish their second round matches already.

I'm aware of the fact that some parts of the brackets will be far ahead of other parts, but I don't really see a problem in that. Anyway, for the others: don't feel rushed, it's just to avoid problems in the next rounds. The deadline of the 21st still stands.

(9 of 16 matches have been played so far)
