RainLoop webmail support / CustomBuild

I came across the following webmail software project:

-RainLoop
https://www.rainloop.net

-Demo:
https://mail.rainloop.net

The demo looks very good. Also full mobile support. Now that RoundCube is the only mode software package in DirectAdmin, is it worth considering supporting it in CustomBuild?

And yes, I know that it is also possible to install this manually! But if it works well it might be nice to have a second choice next to RoundCube which you can easily install in CustomBuild.
