[Star Trek] How much does Starfleet know about the multiverse?

Not the Mirror Verses (I insist that there's multiple) or Yesterday's Enterprise style time travel, but the myriad universes like from Worf's day in TNG's *Parallels*. Has anything been referenced in alpha or beta canon?

TNG's *Parallels* is alpha canon itself. Worf most likely made a full report when he returned to the Enterprise. The viability of it all would have been verified by Data, and it was no doubt sent back to Starfleet where some department or group investigated the full implications.
