-: The maximum packet size parameter is an integer value that limits the size of
-  packets that the endpoint is willing to receive.  This indicates that packets
-  larger than this limit will be dropped.  The default for this parameter is the
-  maximum permitted UDP payload of 65527.  Values below 1200 are invalid.  This
-  limit only applies to protected packets ({{packet-protected}}).
+: The maximum udp size parameter is an integer value that limits the size of
+  UDP payloads that the endpoint is willing to receive.  This indicates that
+  packets larger than this limit are likely not to be processed by the receiver.

@DavidSchinazi I totally agree with your rationale. However, #3447 discusses about enforcing the maximum at the QUIC packet level.

Anyways, regarding enforcement, I think what we need to build consensus, before discussing how it should be baked into the specification. And that might be out-of-scope for a PR that aims to be editorial. Based on that view, I think it is fine to just talk about UDP payload size here, and that having only the text you proposed is fine.
