More of an issue of parsing, I think.. Whether it can be done reliably.
I usually can't calculate dec -> hex translation of arbitrary IPv4 address
in my head :-), and from user's point of view, being able to do like:
ping6 2002:113.114.115.117::1 would help some, especially if we try to get
away from using compatible addresses; if so, this would be almost a
requirement.
I don't see source for big confusion as long as you assume that dotted
quad always replaces 32 bits of the address e.g. with zero-filling (same
if you now e.g. 'ping 10.10').
