I don't lose any sleep over it, but I think IPv6 should *never* show a 
netmask. Ever.

As for caseness:

* I'm fine with lower case as per the RFC.

* If we're looking at this, then maybe the same should apply to MAC 
addresses too.

* I note that MAC addresses are lower case when shown by ifconfig / arp 
under Linux.

* IOS also uses lower case for MAC addresses, but upper case for IPv6 
addresses

rtr1#sh ipv6 neighbors
IPv6 Address                              Age Link-layer Addr State 
Interface
FE80::EEBD:1DFF:FEF9:BAD9                   0 ecbd.1df9.bad9  REACH Gi0/0

So you can never be 100% consistent :-(

Regards,

Brian.
