Specifically, you need to keep ranges unless you have other means of ensuring that you don't accept packets from those ranges again. You also need to keep the largest acknowledged so that you can get a packet number from subsequent packets. This also recommends that ACK frames include the largest acknowledged always. That is primarily to ensure that ECN works properly, and even there, you only disable ECN if you get some weird reordering, so it's probably not a big deal if you don't follow this recommendation. Closes #3541. Closes #3537.
