Agreed.

I find the idea of some secret policeman urging the use of MySQL
because it doesn't have a built-in SHA-1 cryptographic hash function
seems extremely far-fetched. The BitTorrent protocol uses SHA-1 to
validate chunks, and it has been variously estimated that 10% - 50% of
all internet traffic is BitTorrent traffic. SHA-1 is also integral to
the way that git makes content effectively tamper-proof:
