/**
* Remote profiles are inspected from the most to the least
* relevant according to the protocols they belong.
* preferred according to the protocols they belong and age.
* Invariants:
* - `seen_local` array: The most recent profile inside of a certain protocol
* - global `seen` array: The most relevant profile (if there were duplicates, the first protocol of the list is the one to have its profile maintained)
* We do so while maintaining a global 'seen' array makes it
* easy to satisfy a policy of maintaining only the duplicated
* profiles that are either the most relevant or the newest
* - `seen_local` array: The most recent profile inside of a certain protocol are kept
* - global `seen` array: The most relevant profile (if there were duplicates, the first protocol of the list is the one to have its profile maintained) are kept
* These two variables make it easy to satisfy a policy of maintaining
* only the profiles that are either the most relevant or the newest
* ones intra-protocol wise.
