Maven bom is a way to declare a collection of artifacts with a specific version of each artifact which is recommended to use with another artifact from the same collection.

Consider support for it, maybe in maven_install we can create a target a bom, which specified should allow declaring a versionless artifact. Technically this is not versionless like maven RELEASE/LATEST and it will be a deterministic and idempotent build, the only difference is artifact pinning is happening based on an external definition.
