Encourage operators to ignore bridge flags on relay search
The bridge flags on relay search confuse some bridge operators: https://lists.torproject.org/pipermail/tor-relays/2020-February/018188.html
Can we grey them out, or otherwise indicate that they're not used by clients?
Can we change the mouseover help message on the "flags" heading for bridges?
Can we also change the definition of Flags, and the Bridge Descriptors definition, so they talk about bridge flags?
