I'm an extremely occasional nmap user, what benefits would being async provide?

  You don't have to wait for requests to complete, so slow or broken connections don't cause hangs. IIRC, zmap[1] takes this approach. This allows the "probe" stage to be executed essentially as quickly as you can send packets, while you lazy load the results [1] https://zmap.io/ https://zmap.io/

    nmap dev here. Nmap is already asynchronous, as you described multiple requests are multiplexed (cf select(2), epoll(7), kqueue/kevent depending on your platform...) The core difference between nmap and zmap is that the latter is stateless. Which allows a much higher throughput, but also prevents from applying some smart detection mechanisms. Thus, both tools are complementary, and no, there is no work being done to make nmap stateless.
