Comment (by teor):
Our acceptance criteria for sbws is a 50% variance from the consensus,
because that's what torflow's variance was before we started deploying
sbws. See #27339.
Replying to [comment:9 starlight]:
> Defect is extremely severe. SBWS should be removed from production
until this is fixed.
This defect has a limited impact. So we won't remove sbws from production.
> Longclaw has thirteen percent of listed relays with incorrect descriptor
information more than 7% away from the published consensus.
Why pick 7%?
The total consensus weight of the bandwidth authorities now varies by up
to +43%, -14% from the consensus.
