After a quick but thorough conversation with Gustavo we agreed that this is the wrong path to take as it might not be deterministic or people might get surprised about things included that shouldn't have been.

There needs to be a clear line between `build-packages` and `stage-packages`. With that in mind snapcraft (even for `strict` snaps) will still crawl all the libraries and error on missing ones with a list of those that are missing. This should be something one can disable and set to ignore as some of the missing libraries might be provided by a content interface slot from another snap.
