From my research, various authorities have recommended that a single /64 be allocated to router loopbacks with 
/128s assigned on interfaces.

Yes, this is what I advocate for loopbacks.

I often use the first /64 for loopbacks. Loopbacks are often used for management, iBGP etc and having short and easy to 
read addresses can be helpful. Something like 2001:db8::1 is easier to remember and type correctly than e.g. 
2001:db8:18ba:ff42::1 :)

Cheers,
Sander
