Answer 1

As per this answer, you should:

Unsubscribe from the ActivatedRoute observables like route.params if they are subscribed inside a nested (Added inside tpl with the component selector) or dynamic component as they may be subscribed many times as long as the parent/host component exists. No need to unsubscribe from them in other scenarios as mentioned in the quote above from Routing & Navigation docs.
