Understood. The part that the backend can do (these are the files
needed for the build process) is done via the hook. The rest (add
files requested by the user, generate metadata, ...) is backend
independent (or covered by a separate hook/not specified yet in the
case of metadata) and so should be done by the frontend tool.

PS When did Travis become a frontend? I'd have assumed that to produce
a sdist, Travis would *invoke* a frontend tool, such as "twine sdist".
Or am I unaware of some capability of Travis (highly likely)?
