> what is "ACID" isn't even defined.

The docs assume that basic knowledge ...

Atomicity: Either the entire transaction executes, or none of it does.

Consistency: No transaction can break the integrity constraints of the database.

Isolation: no operation outside the transaction can see its intermediate results.

Durability: Once the user is notified of success, the operation cannot be rolled back.

Saying serialisation isolation level is required means the system's behaviour is undefined when that requirement isn't met. Asking MySQL to define what is not defined does not look useful.
