Suppose Dumbledore thinks his enemies aren’t aware that the map exists. If he believes one of his enemies is a Legilimens and is periodically scanning the students’ minds, he might not want to take the risk of them scanning the Weasley twins and discovering the existence of the map. But I admit I’m stretching at this point.

If that enemy exists, he already knows.
Upvoted for qualifying the clever argument with the admission that it is a stretch.
