Two final comments, sorry:

* EDITORIAL/PROTOCOL: Shouldn't the option (as well as the draft) be renamed from "keepalive" to "timeout"? 
To my understanding "keepalive" would refer to a mechanism where "empty, ping style packets" would be used to 
keep the session established, and be misleading for a mechanism to negotiate timeout values... change to 
"edns-tcp-timeout" Option, and according draft name?

* PROTOCOL: Are there any race conditions when this Option is used in conjunction with 
Ray's "Connection Close" flag 
(https://tools.ietf.org/html/draft-bellis-dnsop-connection-close-00)?

The two options are alternative proposals - there should never be a reality where both proposals exist as supported options.
