Shouldn't the boolean validator be consistent with the boolean method?

Hi,
Firstly, I know there are accepted and rejected validators, but....
The $request->boolean() method uses FILTER_VALIDATE_BOOLEAN which in turn returns ‘1’, ‘true’, ‘on’ and ‘yes’ for true. The boolean validator on the other hand only uses true, 1 and ‘1’. This causes an inconsistency for e.g. checkboxes (but also for the Postgres database, for which the boolean true is 1, true, on, yes), because a checked checkbox will be rejected by the validator, but $request->boolean(‘checkbox’) will return true/false for on/off.
Wouldn't it be better to make this behaviour consistent and thus simplify the validation too?
