We've been doing this for years on both Juniper & IOS/IOS-XR devices.  Must be someone else.

We do run into this whole feature parity thing often.  The vendors seem to be challenged in this space.  I suspect a 
significant part of it is they don't actually *use* IPv6 internally or in their lab.  We have been operating our 
network with IPv6 for many years now.  I believe in most cases our connection to the management plane go IPv6 only as 
well.

It's been fun to see the few SSH over IPv6 defects and other elements arise as time has passed, but those days are 
over.  It's just tiring now and no longer amusing.  (hey you kids, get off my lawn?).
