> Hannes: do you have any opinion about the necessity of going through /.well-known/core to get the short URL, vs just using a /.well-known/est URL?
(RTT for the lookup vs extra bytes in the URL)

Are you asking me about these two options:

Option #1 - going through /.well-known/core

     REQ: GET /.well-known/core?rt=ace.est

     RES: 2.05 Content
   </est-root >; rt="ace.est"



Option #2 - using a /.well-known/est URL

     REQ: GET /.well-known/est

     RES: 2.05 Content
   </est-root>; rt="ace.est"
