I agree it's useful.

I wonder if we can abstract some of these functions to be able to run
some of them without the actual build - we want to generate BOM (Bill of
materials) before building the image and e.g. for verification builds we
generate them twice (for base metadata, then with verification changes
applied) and generate diff.

I've implemented this as separate task which traverse the dependency
tree from the image we're going to build and writes all interesting
metadata in JSON.
