Hi Zahed,

Thank you for your review!

Regarding the DISCUSS point, I totally agree with you, this was an
oversight on my part. I'm fixing it in this PR:
https://github.com/ietf-wg-masque/draft-ietf-masque-connect-udp/pull/178
Could you please take a look and let me know if it addresses your DISCUSS
fully?

I'll address the COMMENT portion of your review in a subsequent PR and I'll
reply here when that's ready.

Thanks,
David
