I agree. I see no reason to distinguish in this case. IMHO, this
policy should apply to ALL addresses returned to ARIN.

I agree that this provides clear instruction. What I still don't
understand is why that instruction should apply only to "legacy"

I think it would be much easier to simply remove the word legacy from
this text and make it apply to all resources.
