You might be waiting some time, as we've already triaged tasks for the next Tor release 0.2.9, which comes out in 6 months. The relay's IPv4 address may be blocked in some jurisdictions, but not others. So it still could be useful for some users. And the bridge's IPv6 address is far less likely to be blocked, so it will be useful by itself. Please also note that you can have a maximum of 2 relays per IPv4 address (or a relay and a bridge), on different ports.
