RE: Services matched by script--show a service fingerprint?

If it's a hard match by the NSE script then I'd like to see it hide the
fingerprint.

Subject: Services matched by script--show a service fingerprint?

Dhruval Gandhi's screenshot at http://seclists.org/nmap-dev/2011/q1/1014
shows port 80 being matched as skype2 by the skypev2-version.nse script, but
a service fingerprint is being shown anyway.

We usually get a bunch of Skype service submissions in each batch, which I
have to ignore because service detection can't match it (that's what
skypev2-version.nse is for, after all). I thought that perhaps the script
was failing for some reason, but now I see that if a service produces
output, it can cause a fingerprint to be displayed even when a script later
matches the service.

Should it work this way? How about hiding the fingerprint (and request to
submit it) when a service is hardmatched by NSE?
