Yeah, I think it would be a great idea to link to that from the build
configuration page in the Spectrum documentation, as an example.

To clarify, I don't expect the *generic* x86_64 image to use a build
configuration file, nor would I expect a generic aarch64 image to.
The build configuration file is there for when it's neccesary to
override the defaults, for example to use a custom kernel.  (But it
would also make sense to have a commented *example* build configuration
file in the Spectrum repo, to be a starting point for users.)
