security endpoint does not require system extension?

I was under the impression that a security endpoint required a system extension, but that does not appear to be the case. Apparently daemons can create endpoint extensions without needed a system extension. Why would I use an endpoint in a system extension rather than a daemon, or vice versa? I'm not understanding the value of a system extension with regards to a security endpoint. Someone please enlighten me.

How do I change the system extension in the SimpleFirewall example to endpoint security?

I'm trying to learn system extensions through fiddling. One thing I'm trying to do is take the existing SimpleFirewall code project and make it endpoint security. The problem is when I remove "Network Extensions" array from the extension entitlement file & add "com.apple.developer.endpoint" to the same entitlement file, I get the following error from sysextd. "System extension does not appear to belong to any extension categories" How do I tell the OS that this is an endpoint sysext? I've changed the plist and entitlement files of both app and extension to look like the endpoint example.
