No integration-area record carries custom fields
Context
Metadata registration alone does not imply custom-field support.
Decision
Keep these objects outside custom-field, configurable-form and configurable-layout support. Registered workflow configuration objects do not enable metadata capabilities.
Alternatives Considered
Enable custom fields on integration configuration. The approved classification does not designate a Platform object for this support.
Consequences
Purpose-built screens use existing shared UI components.
Any new custom-field designation requires an explicit product decision.
