FWIW, sometimes the bundled ‘source’ dependencies contain bundled
binaries of their own.  So while AFAICT not strictly necessary for
reproducible builds, unbundling ‘source dependencies’ makes ensuring
reproducibility(*) much more convenient.

(*) i.e., the non-trivial kind of reproducibility, where things are
actually built from source instead of copying binaries.

It's ‘reproducible’ in the trivial sense that you can ‘reproduce’ a
scientific paper by putting it a photocopier.  That way, you can
reproduce the results, but you cannot confirm whether these results
were correct.
