Hi Sebastian,

Thanks for the feedback.
Regarding IPv4, I believe that technically speaking ICMPv6 Loopback
could be similarly defined in ICMPv4. However, please note that one of
the main benefits of ICMPv6 Loopback is that the reply includes the
IPv6 extensions of the original ICMPv6 request. This would be slightly
less relevant to IPv4, as IPv4 options are not as commonly used.

Cheers,
Tal.

Are there any obvious reasons (factual or procedural) I might be missing why restricting this to ICMPv6 is the best path forward?
