Will a constraint not consume CUP time when it with a zero constraint weight?

Hi, teams,
From the following code, does it mean a constraint wich with a zero constraint weight will be ignored? These constraints will not be included in the score calculation?

https://github.com/TimefoldAI/timefold-solver/blob/8768155a076de1f4b8537fa2ebb62811562e9c67/core/constraint-streams/src/main/java/ai/timefold/solver/constraint/streams/bavet/BavetConstraintSessionFactory.java#L60

Exactly. When a constraint's weight is set to zero, it is completely eliminated from processing, as if it never existed in the first place.

Great, thank you.
We can make constraint customization (such as enable/disable a constraint) more concise through the constraint weight.
