Resource's id that came from Implementation Guides used to keep its original id but now they are stored as random uuid

I just noticed that in 7.6.0, elements from Implementation Guides were stored with its original id like this:

{ "fullUrl": "http://localhost:8083/fhir/ValueSet/be-civilstate", "resource": { "resourceType": "ValueSet", "id": "be-civilstate", "meta": { "versionId": "1", "lastUpdated": "2025-11-26T11:14:51.756+01:00" },

But now, in 8.6.0, the elements are stored under random uuid id's like this:

{ "fullUrl": "http://localhost:8083/fhir/ValueSet/3ad39429-aa02-4d60-a5fc-0798a793382a", "resource": { "resourceType": "ValueSet", "id": "3ad39429-aa02-4d60-a5fc-0798a793382a", "meta": { "versionId": "1", "lastUpdated": "2025-11-26T11:22:44.262+01:00" },

Is this a bug or is it on purpose ? Is it configurable somewhere in the new application.yaml ?

Thanks,

Marcelo
