I was doing the same! I then started a rework a couple years ago to
implement this idea.. At that time, I was less experienced and did not
fully understood Kbuild. The result worked but was ugly and stayed in my
local tree.

This winter holidays, I had a bit of free time, revisited my old idea,
and this time, found something I thought was worth upstreaming. Thus
this series.
