Does it block `/etc//hosts` or `/etc/./hosts`? This is a ridiculous kind of whack-a-mole that's doomed to failure. The people who wrote these should realize that hackers are smarter and more determined than they are and you should only rely on proven security, like not executing untrusted input.

No one expects any WAF to be a 100% solution that catches all exfiltration attempts ever, and it should not be treated this way. But having it is generally better than not having it.

Is it? The WAF is also now an attack surface itself, and I don't think WAFs have exactly proven themselves as something that meaningfully increases security. They certainly break things unpredictably, though.
