Subject: A few questions regarding the newly added BLAKE2 format

Hi all,

I commented on the recent commit "Add support for BLAKE2 hash function
(https://blake2.net/)", 2620ccc0394051a2e34ac4873fb905d2af18f9ce, on
github, but magnum suggested to take this discussion to john-dev or
john-users, so here we go:

Is BLAKE2 really used as a password hash algorithm? If so, where?

Should we really allow newly added formats to treat ambiguous hashes as
valid?
The hash
4245af08b46fbb290222ab8a68613621d92ce78577152d712467742417ebc1153668f1c9e1ec1e152a32a9c242dc686d175e087906377f0c483c5be2cb68953e
is considered as valid by raw-sha512 and more than 20 dynamic formats.

Frank
