Hello, I'm performing bug triage of the nmap package and I would like to address this one.
This is something that should be forwarded upstream. It looks like there is some kind of support for using /etc/services already[0] The ideal solution IMO is to fallback to /etc/services when the service is not already* on nmap-services[1] because the latter has a weight (open-frequency). I will have a further look into this and create an issue upstream. Thanks for reporting it.
