Thing is depending on a future update rumour may not yield fruit @AlexyN9
I've no idea why Samsung would not provide Goodlock for your phone model unless they deem it wouldn't be able to run it etc.
It's the same as Samsung don't allow Goodlock in some regions.
Is there another option you could look at that brings to the table the same way Goodlock does.
Nova Prime or an app etc ?
I wish you all the best with this.
