What is true today may not be true tomorrow. Regardless of the number of new
exchanges coming on board, I still believe that a /24 is a reasonable minimum
assignment.
IPv4 should have been over quite some time ago. It’s relatively trivial to
exchange dual-stack NLRI over multi-protocol BGP over IPv6.
On Juniper, this looks like this:
protocols { bgp { group <name> {
neighbor <peer-v6-address> {
local-address <local-v6-address>;
family inet {
unicast;
}
family inet6 {
unicast;
}
}
} } }
There’s a similar construct available for FRR, Cisco, Arista, and many others
as well.

I strongly oppose this for the reasons stated above.

I am slightly less opposed to this so long as it comes with additional
instructions to ARIN staff to:
1. Reserve the remainder of the corresponding /24 for each longer
prefix issued until such time as there
are no available /24s to issue.
2. Expand the prefix to /24 upon request from the IX without any
additional justification required.
