Hmm, so it's basically "the person doing the configuration needs
to know what they're doing, the Kconfig system will give them
no hints about what devices might or might not be needed to
make machine type M functional" ?
It depends on what you mean by functional. I would say you do get what
is needed to have a functional machine, but not what is needed to have a
useful machine.
If you need to pass '-nodefaults' to get the thing to start up at
all, that seems to be stretching the definition of "functional"
to me.
Then, an accurate description that uses "functional" in that sense could
be as follows:
The Kconfig system will include any devices and subsystems that are
mandatory for a given machine type, and will flag any configuration
conflicts. However, the person doing the configuration still needs to
know which devices are needed (on top of the mandatory ones) to obtain a
functional guest, and Kconfig will not provide any hints in this respect.
