Pricing Opt-in Feature: Should we enable this ?

Summary:

Hi Team,

I can see this feature in Opt In: Order Management : Pricing, the definition for this feature as per Oracle Docs is as below:

Use the set up in the Pricing Administration work area to price items in Order Management. Leave this feature enabled unless you plan to use some other way to price your sales orders.

We don't have this Flag checked in our environment, however still pricing and discounting is working fine.

QUESTION: Should we enable this checkbox ? What is the use/feature of this checkbox ?

Kindly do let me know if any other details are needed from my end.
