This list context idea doesn't appear to have anything to do with the requirements for a "hook" for this terminal emulator. The hook returns something that is evaluated in a scalar context. When the hook fails, it should: return 1;. The suggestion for when the hook succeeds is to end the sub with simply (), instead of even a return! Ok, if that is what you want to do, then I would agree that "return;" is better than a simple "()". Perl will return the value of the last statement in a sub if there is no explicit return. I argue that return (0); is better than a simple () or bare "return;" when the objective is to return a simple scalar true/false.

One of the pages that talks about this: Hooks. You can see some examples of code at Example Hook Code. It is clear to me that the intent is a simple true/false that will be evaluated in a scalar, not list context.
