Cool, pretty much like kernel some modules then.

That is a Good Thing :)

Let's say that, in the best case scenario, that Nvidia updates both
their new and legacy drivers (71xx,96xx). Still the relevant Debian
packages can't be installed at same time (as they are now), so the
proper nvidia driver sporting the proper PCI ID might not be available
on the system. Is there a workaround for this?
For example in the Debian package for a legacy driver one could change
the path of the file of the nvidia xorg driver, from:
/usr/lib/xorg/modules/drivers/nvidia_drv.so
to
/usr/lib/xorg/modules/drivers/nvidia_drv-96xx-.so
so that the package doesn't conflict anymore with the other nvidia
driver packages. Or other tricks like this one.
Would this work/make sense?

In the worst case scenario of Nvidia not updating their drivers (or
updating only the new one and not the legacy ones), what could be done
to avoid the user to edit directly the xorg.conf file?
