It's useful to hide the indirect function call with either static inline
or a macro. This reduces programming errors, hides the "method" used
to access the indirect function and defines the "API" for a layer of code.

I asked the same question about 4 monthes ago for a different
"jump table". If a function is "required", then supplying a default
function call is practical (and my preference too).
