Why is do you prefer that?
Keyways not only allow for controlled joints, but the shape of the keyway has a "c channel" built in which helps prevent either side of the control joint from sinking or rising independently. Both sides of the joint "lock in" to the keyway similar to dowelling.
A regular saw cut joint is completely at the mercy of the substrate. This is actually the cheaper way to do it. Metal keyway costs around $10 per stick (10ft) plus cost of stakes.
Let them know if you'd rather cut joints and it should save you money. If thats your preference.

I see. Originally I thought control joints in addition to keyways. But you’re saying it’s either one or the other.
