We have observed at least one FTL phenomenon -- sort of. We know entangled particles communicate with each other FTL because of the Bell inequality. We just don't have any influence on what message they communicate (and we probably never will).

Isn't it just due to specific interpretations of QM that particles communicate? The Many-Worlds interpretation (also pilot-wave theories) wouldn't require any FTL communication between particles.
