Except if the hash is SHA1 (or any other non-compromised cryptographic hash) they would have a very difficult time creating requests that yield the same hash, that aren't the same request, right?

I'm not sure, but I think if you're just interested in creating N collisions, as opposed to finding something that collides with given plaintext X, that the birthday paradox gives you a huge performance increase and makes it feasible. Also, I think many still use MD5 in applications where SipHash is intended (at least the Linux kernel does).
