Null Components should never have children - they'd never be rendered.

Aligning closely with the <Injector_ > naming convention, Null Components are denoted with a prefix and postfix _ (e.g. <_NullComponent_ />).

The idea is that the additional prefix _ of a Null Component symbolizes that it adds even less to the DOM than an Injector. I picture the name falling through to become just the _, like the unused argument convention in javascript functions: const handleEvent = (_, id) => { console.log(id) } .
