Yes, you are right - enabling safe checks will limit the effectiveness
of the script. However, radmin is not a backdoor but an administration
service.
Even if we can identify snmpdm, I think I'll continue to have this
script castrated when running in safe checks, as I have had at least one
report of another service crashing because of it (binary protocols
negocation tend to break a lot of things).
Once again, we're facing a balance of intrusiveness vs. accuracy of the
scanners, that the way it goes.
