Why? It's better and more shiny than regular ping. You can for instance ping several adresses at one.
Open Source? liboping is distributed under the LGPL 2.1. The oping and noping utilities are licensed under the GPL 2.
How many users will use? Hopefully many because pinging is essential and noping does that very well.

This has sat in accepted for inclusion for 6 months now. Clearly, there is a lack of demand for the inclusion of this software, nobody has stepped up to provide a patch, maintain it, and properly integrate it. Closing as a result. Feel free to reopen but only when someone offers a patch via our proper patch submission methods and volunteers to be maintainer.
