Correct this will address my DISCUSS point if you also modify the line below,
i.e., replace all IGMP by IGMP/MLD in the text until the terminology section
states "IGMP means IGMP or MLD" (sic).

Hi Eric,
These hosts/VMs express their interests in multicast groups on a
given subnet/VLAN by sending IGMP Membership Reports (Joins) for. >> Adding
MLD here too ?
their interested multicast group(s). Furthermore, an IGMP router
periodically sends membership queries to find out if there are hosts
on that subnet that are still interested in receiving multicast
traffic for that group. The IGMP/MLD Proxy solution described in
this draft accomplishes has three objectives:
does this change look ok ?

Hello John,
Thanks for your quick reply, even if I am unsure how to read " Yours
Irrespectively," as I am not an English-native person.
Thank you for pointing me to the new sections 9.1.2 & others => I will update
my DISCUSS on this point w/o sending another email.
But section 1 still mentions only IGMP and never MLD except for "IGMP/MLD"
proxy, this is trivial to fix, so I suggest to the authors to update the draft.
Regards

[JD] We added:
9.1.2. Reconstructing IGMP / MLD Membership Reports from Selective
Multicast Route
9.2.2. Reconstructing IGMP / MLD Membership Reports from Multicast
Membership Report Sync Route
9.3.2. Reconstructing IGMP / MLD Leave from Multicast Leave Sync Route

[JD] The Abstract states: This document describes how to support
efficiently endpoints running IGMP
(Internet Group Management Protocol) or MLD (Multicast Listener Discovery)
for the multicast services
over an EVPN network by incorporating IGMP/MLD proxy procedures on EVPN
(Ethernet VPN) PEs.
We also added this paragraph to section 3 at Ben's behest:
It is important to note when there is text considering whether a PE
indicates support for IGMP proxying,
the corresponding behavior has a natural analogue for indication of support
for MLD proxying, and the
analogous requirements apply as well.
