The 747 from Qatar is not going to be used as AF1 any time soon, I'm reasonably confident.
It is being donated because the aircraft is an impractical beast, even for royal transport, and I think it is going to have a special role, or cluster of roles, in upcoming events.
I am imagining that the aircraft could be used as a enormous courtesy coach, bringing together parties to momentous events. It could be the dramatic setting for the signing of some historic agreement.

This instantly transforms the luxury albatross into a historical jewel, and Qatar gets a warm and fuzzy, including a nice static display with a plaque saying nice things about them.
Look up the amount of Qatari money poured into the USA for various influence programs before you decide how you feel about the whole thing.
Of course, Trump is RELISHING giving Boeing a bit of the boot with the issue.
They need to bend the knee multiple times and get busy re-earning "if it ain't Boeing, I ain't going".
