Touche.
I like those hashes. Why don't we use the entire alphabet. Base64 would be cool.
Way harder to remember a hash using base64. Hex is much more manageable and you still only need to remember 4-5 digits usually.
If it is about memory, why not generate 4 or so words as the 'visual' hash, which is probably good enough for most teams to use for branching/merging without experiencing clashes.
