So you're saying you want the message re-worded?

I doubt it? I'm not sure yet how we address getting buildman to know
about valid additional combinations. Take the example of something like:
som_vendor_carrier_defconfig + som_vendor_imx7_som.config +
emmc_boot_instead.config + customer_production_tweaks.config

How would you want buildman to know about that? Does it even really need
to, on the other hand?  And that's not I think an uncommon example, it's
just splitting colibri_imx7_emmc_defconfig in to how it would be used by
someone taking that carrier+som to production, with their own
touchscreen and a few other tweaks in the dtb that needs to be passed to
linux.  Or the mnt reform with whatever SOM/COM you happen to have for
it.
