The sentiment should be "write your own code, but don't use it without independent audit". There's another recent discussion about it here: https://www.reddit.com/r/crypto/comments/418nyl/write_crypto...

People write their own toy kernels or malloc()s all the time, and there's never the assumption that they would actually try to use them for real, and the security implications are just as real there as for toy crypto.
