Let's imagine you install modules pkg first, then dkms pkg, which skips building because you have
"same" modules installed. After some days you accidentally uninstalled the modules pkg, then how
would the dkms pkg know and start the building? There is no such mechanism according to my knowledge.

Even though such mechanism can be implemented by dkms, let's dig deeper into details: how would dkms
know that your prebuilt version and dkms source files are "the exact same" and decide to skip? Designing
such a mechanism would be either cumbersome for developers, or confusing for users, I suppose.
