Think about companies deploing binary only drivers for their hardware.
I guess they'd be happy to have a 'feature' like this in the kernel.
We might end up with hardware companies deploying binary only signed
modules for the major distributions (with which they have deals).
We might end up with weird patches from those companies to get their key
into the kernel source in order to be able to load their signed module.
Once a module itself requires this feature in the kernel you don't have
the choice of saying 'No' to this option of compile time and you can't
simply revert this patch anymore as others have suggested.
This patch would give power to those who make binary distributions and
(binary only) modules not to the admin who runs the system.
Only allowing modules to be loaded from a secured area (read only
device, signed 'container' of modules...) and leaving it to the
admin which modules he puts into this area would address all the reasons
for this patch without taking power away from the owner of the system.
