I'm not against keeping some around, but this warning is unlikely to turn around the thousands that currently match this configuration--hopefully it'll just encourage future bridge operators to use a 'safer' configuration. The obfs4proxy README shows users how to set-up obfs4 running over port 443 which is probably the most desirable option: those users can evade network restrictions without enabling discovery by scanning.

I've attached a patch to warn bridge operators running with ORPort set to 443 or 9001 as a stop-gap measure.
You are raising good points here but keep in mind that we also want at least *some* (vanilla) bridges which run on port 443. There are some adversaries such as captive portals which only allow communication over a small set of ports and 443 is one of these ports. While these bridges would easily fall prey to Internet-wide scanning, they would still be useful for users behind captive portals.
