 - there is no address scarcity with IPv6 (at least not in the sense that there is with v4)
 - there is no significant danger of unconstrained v6 RIB explosion when assigning PI prefix to people who already occupy at least one slot in the v4 table (the problem is constrained to be at worst as bad as we see with v4, which is a known ceiling)
 - there's minimal administrative overhead in assigning PI space to people who are unlikely ever to come back to ask for more
 - what administrative overhead there is is minimal if the process of justification is trivial (or automatic)
 - ARIN says it is in the business of encouraging people to use v6
 - people are more likely to use v6 if they can get v6 addresses easily and cheaply

So automatically assigning v6 addresses to people who have a history of advertising v4 prefixes seems like it has minimal cost (less cost than other assignment strategies, seems to me) minimal risk to the Internet and will encourage people to use v6.

What rationalisation can you provide for not doing this?
