Even non-cryptographic hashes must provide some sort of security against attacks. Let's say we use a weak hash function in an open addressing hash-map - if I can calculate a set of inputs that will all collide in the hash-map, then it will turn the O(1) lookup into a O(n) lookup. If a small change to the seed mixing (literally moving a line from the end to the beginning of the function) increases the security with no penalty to performance, then we might as well make the change.
