I really appreciate your security worries and i would see more checks like this for all the crucial packages we have here.

Latest package followed the insane approach to make an intense use of sudo because the previous one was prepared in the same way and evaluating the long time since last update the painless step and more reasonable way (to me) was to pick up the package and update following the previous situation.

Now, since all the feedback received here sounds like a silent/consent to the last package version, we (I / YOU) can proceed with further changes.

Anyway, i think that have an updated nmap version is very important considering the package purpose and leaving it there "just sleeping" for 3 years sounds like abandoned and not acceptable.

I was expecting for the new version 6.47 to be released to prepare another package, but, if you have more time than me to take care of it, as older maintainer, feel free to go ahead!
