Well, if you want to be really environmentally conscious, do away
with that /126 too and just use link-locals, with a single global

link-locals?)
You don't. I don't think the point of link-locals has much to do with pinging customers... But since IPv6 routing protocols work over link- locals you don't need global addresses.

If you want to ping your customers you should probably use a /126 so they can only use the specific address you give them. You need that anyway if you want to route a /48 or what have you to them.

BTW, there is discussion about rethinking /48s for customers in IPv6. Thoughts?
