I'd like to review the history of this and make sure that it's no longer necessary.

Ok, this guard is extremely old (from this change) and I think is just no longer necessary.

This shouldn't have any functional change, but it refactors a bunch of methods which currently return a value or
falseto return a value ornull. Since PHP 7.1 supports nullable return types, this pattern has been shown to be more standard than the ... "falsable" 🤔 return type that I had been using to signal failure.
