Related question: Should OpenMLS check for these limits or rely on the crypto provider?

No particular opinion on who should keep track of this. But I'm wondering, where this is relevant. If I understand correctly, these limits are per key. And due to the sender ratchets, we use each symmetric key exactly one time. Is MLS using AEAD in other places?
