Yes, be careful when using ForwardAgent and, more importantly, avoid using it altogether unless you absolutely need to! Most "use cases" I've come across could have been solved "better" by simply using ProxyCommand instead. That was apparently too hard, though, so use of agent forwarding continued. Since the introduction of ProxyJump a while back, however, it's now even easier to avoid using agent forwarding in most -- but not all -- cases. So yes, be careful when using agent forwarding but, more importantly, as much as possible, just avoid using it entirely unless you absolutely must!
