<p>On the receiving size, do you see an advantage in that separation in practice?</p>
</blockquote>
<p dir="auto">RFC 8470 actually suggests that the server could defer processing of early data only after the handshake is completed, to mitigate the replay risks in case the anti-replay measure doesn't work.</p>
<p dir="auto">In any case, I think the current API is sufficient to cover both use-cases; maybe later, we could add convenient API on top of it.</p>
