Honestly, I think that yesno() is much easier to understand than %py.
And %py[DOY] looks really scary. It has been suggested at
https://lore.kernel.org/lkml/YCqaNnr7ynRydczE@smile.fi.intel.com/#t

Yes, enabledisable() is hard to parse but it is still self-explaining
and can be found easily by cscope. On the contrary, %pyD will likely
print some python code and it is not clear if it would be compatible
with v3. I am just kidding but you get the picture.
