Hi Eduardo,
thanks for being interested in the proposal.
Please find my comments inline.

Hi Mario,
I glimpsed at your presentation today in ROW but I wasn't able to
comment it live because I was in another meeting......
So what you purpose is to change the transport method from TCP do HTTP.
[ML] No. We propose another mapping in addition to TCP. If RFC 5730
states that it is possible to map EPP over various transports, this is
just one of the possible mappings.
I understand that this a good starting point but is it enough? EPP
over TCP is a barrier for getting new Registrar and I suspect that
moving it over HTTP wouldn't change that much. EPP is about 20 years
old and I think it needs some reshaping to the actual Internet state.
[ML] Based on the experience of both .pl and .it, implementing EPP over
HTTP is much easier than TCP over EPP.
From client side, you don't need to manage connections but you are only
required to send a request and process the response.
Besides, sessions are implicitly handled by the libraries just enabling
cookie management. Just to give an example, .it has developed a Java
client library for .it registrars that have easily incorporated it in
their own client applications for their users.
Likewise, from server side. Decoupling the session from a physical
connection makes the sessions more flexible.
Please take a look at the section about load balancing included in the
draft to know what I mean.
As i said at the meeting, the proposal aims at defining rules for
mapping EPP over HTTP as a psedotransport. In that sense, the proposal
is very conservatve.
We didn't mean to be revolutionary. Our goal is simply to define another
mapping that preserves EPP commands semantics.
Was this a discussion that the community had? (Probably the community
had it and I was just not alert, since I'm not that active...)
Tell me your thoughts!
[ML] My impression is that most of the attendees didn't catch the
message above. Most likely I ddn't make myself clear.
I fully agree with you that if there is an emerging requirement to
refactor EPP, such a proposal isn't enough and a more exhaustive
document (or a set of documents) should be written.
Best,
Mario

Hi folks,
in view of the panel about epp-over-http at next ROW, I just
published version -02.
In addition to having updated some references, the mapping
considerations have been rearranged on the premise that HTTP is an L7
protocol used for pseudotransport.
Feedback either on this mailinglist or at next ROW is welcomed and
appreciated.
Best,
Mario

Revision: 02
Title: Extensible Provisioning Protocol (EPP) Mapping over HTTP
Document date: 2022-06-13
Group: Individual Submission
Pages: 15
URL:
https://www.ietf.org/archive/id/draft-loffredo-regext-epp-over-http-02.txt
Status:
https://datatracker.ietf.org/doc/draft-loffredo-regext-epp-over-http/

Diff:
https://www.ietf.org/rfcdiff?url2=draft-loffredo-regext-epp-over-http-02
Abstract:
This document describes how the Extensible Provisioning Protocol
(EPP) is mapped over the Hypertext Transfer Protocol (HTTP). This
mapping requires the use of the Transport Layer Security (TLS)
protocol to protect information exchanged between an EPP client and
an EPP server.
