Why do some providers require IPv6 /64 PA space to have public whois?

Yes, HE has a one-word peering policy… "YES!"

However, that means that if hetzner peered IPv6 native with us, we
would provide them every thing you get through tunnel broker still
at no cost and without any limitations on bandwidth.

We don't artificially limit the bandwidth on tunnel broker, but, each
tunnel broker server has a single network interface that it hairpins
the v4/v6 traffic on and the bandwidth is what it is. I don't expect
that will be an issue any time soon, but for planning purposes, people
should understand that tunnel broker is a where-is-as-is service on
a best effort basis with no SLA.

We do offer production grade tunnel services for a fee and people
are welcome to contact me off-list for more information.

We would really rather see such traffic come native across our peering
links as much as possible. It allows us to provide a higher quality
of service.

Being a popular IPv6 peer and having so many tunnel broker users has
been a great success story for us, yes. However, in terms of how
this affects our standing for peering, I think that the effect is the
same regardless of whether we are passing the traffic from/to a peering
link or a tunnel broker.
