I think the documentation at:
https://stem.torproject.org/api/descriptor/remote.html#stem.descriptor.remote.Query
is out of date: as far as I know, newer stem versions try fallback
directories rather than authorities.
Even if that's not the case, stem will choose a random authority for
you, which will (8/9 times) tell you that it knows nothing about any
bridge extra infos. (I don't think authorities cache bridge extra
infos.)
Try passing Bifroest's address and DirPort to the endpoints= argument to
get_extrainfo_descriptors():
