It also specifies what drivers attach where. If you have a modular kernel
and want to add a new driver, you could compile it and stick it into the
module directory tree, but if the config file didn't have that module in
it when the kernel was originally built, your driver can never be loaded
and your new device is useless.
config was a solution to the problem of needing to edit headers and source
files to add a new device to the system. In a modular world I think it's
a bit dated and there will be a need to figure all this stuff out
