If I recall correctly, the original motivation of the IXP policy was to allow IXP to get space, even if they did not otherwise qualify to become an LIR. This was so that they could maintain independence from LIR peering at the IXP.
However, there are basically no restrictions on becoming an LIR, and basically no space available. So there is no reason for a special IXP policy.
My own preference is that we stop IXP IPv4 assignments completely. IXP can purchase IPv4 space on the open market the same as everyone else.

I don't typically comment on address policy because it might look self-serving, but someone asked me to comment. Thinking about the costs to set up an IXP, I went back to this RIPE presentation a few years ago: "The $1,000 Internet Exchange" https://ripe71.ripe.net/presentations/30-1000-dollar-exchange-ripe71.pdf Market price for a /24 might be high enough to prevent an IXP from forming. Even a significant subnet might be expensive, and that's if someone was willing and able to sell a /26. Lee
