Hi Lukas

You beat me to it.

Jason, the things to understand is, Wireguard is not finished. It has
only just started. The code will develop further, changes will be
made. We need the code to be easy to make changes to. As Lukas just
pointed out, this number construct is hard to change in a minimal way,
making a patch small, and obviously correct.
