`Mergeable` Apply Requirement is not useful

[pratikmallya]

When the mergeable apply requirement is used AND the atlantis status check is a required check, atlantis will always fail to apply. This is because, as soon as the atlantis apply comment is made, the status of the (required) check turns to pending, thus rendering the commit unmergeable
