Can i only have one Post User Registration Hook active at a time?

I created 2 Post User Registration Hooks. Both work, when I activate them. But why can’t I activate more than one?

One hook makes a call to my application to do some post-registration process. The other hook triggers a slack notification. They do very different things and I’d like to have both and optionally turn one off at a later time.

Is my only option to integrate both into one hook and then manually modify it later if I want to remove one of the functionalities?

For now, only one Hook can be enabled at a time, for each extensibility point.

Correct.
