I went to register a ".app" domain with Route 53 but I was told it was not available.
At first I thought this meant my domain was registered but after some digging it turns out that Amazon just doesn't support the .app tld.

Does Amazon need to pay to be a .app tld registrar? If so, maybe they are waiting until they get enough requests before they pay. It's not clear to me why Amazon would need to work for years to add support for a .app tld. I would think that it would involve just adding a .app value to some list of possible values.
Wikipedia mentions Google purchased the .app tld.

Does that mean adding support for the .app tld would mean paying Google?
Importantly does this impact my ability to link a .app domain (registered with Google) to any Amazon services?
