Deprovisioning is huge. Provisioning is also awfully nice. For example:
1. New employee joins the team.
2. SCIM creates their account in the ticket tracking system.
3. Employee's boss can create onboarding tickets and assign them to the new person before they've even logged into the system.
That's not such a big deal for small companies that don't use a gazillion services. It's huge for large companies with hundreds of vendors where you want everyone in an employee group ("engineering", "sales", "everyone") to have an account in some of those services.
