My understanding of it (although I have not followed it closely) was
that they were looking for a mechanism to specify those things that
should be in the configuration at a high level, that would then lead to
the rest of the dependent items being selected automatically.

So, rather than having a *full* config file (and all the associated
churn as individual settings are changed within the kernel), they would
only have a snippet that selects the specific features for the board,
that would then cascade-select the rest of the settings for a full
kernel config.

That was considered acceptable, afaik.
