Not sure if Vladislav read that, but it might be on us; we were both talking
about a Kconfig in [1] back then, but meant a module param actually. :)

I think for development it doesn't make a huge difference, but a module param
might be easier to deal with if something unexpected happens in some less
controlled environment.

So, while I'm usually not a huge fan of module params, I do agree in this case.
