Let's take an analogue.  Does the same implementation have a global 
configuration to enable/disable BGP?  BGP and BFD sessions seem like 
similar beasts, and similar management techniques apply.

I can only see (real) usefulness for session-based controls (and 
"enable BGP/BFD" toggle without session-specific config is quite 
questionable), but others might have different requirements so this 
isn't really a big issue to get too excited about.
