Possible advantages are:
- Relay Search would support searching for bridges by contact information.
- People who keep a watching eye on the Tor network could reach out to
bridge operators to inform them that they're running an outdated tor/PT version, or that running bridges and exits together is not cool.
some more come to mind:
- we could tell operators of obfs2 and obfs3 bridges that they would be much more useful if they run obfs4 PT (increase the usefulness of current resources)
- we could tell operators that running obfs3 and obfs4 is a bad idea
- we could tell operator that exposing their vanilla ORPort is a bad idea
