I don't know if we are in the minority but you're not alone :)
We are using /64 on all interfaces (ethernet, loopback) just because
the host id is defined as 64 bits.

>From time to time I see discussions if anything other than /64 is harmful
or not. But I can't remember any discussion if /64 is harmful. For me this
is a reason to keep on using /64.

If anyone sees problems with /64 except possible loops on p2p interfaces
(sdh world,...) please let me know.

regards,
Michael
