With current addressing scheme we only have 2^13 times more site addresses than IPv4, which is plenty in absolute numbers, but not necessarily enough for more coarse aggregation, and definitely not infinitely future proof.
replyCrucially though, if we change it, we just have to change how addresses are allocated, not change the protocol again.

replyYup, and only less than an eighth of the total IPv6 address space has been allocated [0] [1], so there's still plenty of room to expand, even if we have to throw every current address out and start from scratch.

replyMine all have link-local addresses (I do have a real static IPv6 address block from my ISP, at great expense…) - so I’m not sure what I did wrong in my Ubiquiti gear.
A link-local address is required with IPv6, so your devices probably just have that in addition to a globally-routable IPv6 address. This isn't a problem though, since devices have no problem having lots of different addresses on the same interface [0].
