This seems like a distinct operation from 'prepare the files needed to
build a wheel', although they are related. For instance, sdists
typically contain docs (in source form), but you don't need these to
build a wheel. It would be fairly easy for Flit to identify the files
needed to build a wheel, but it can only identify the files needed for
an sdist with the help of a VCS.

Would you be happy with a compromise where PEP 517 defines a (possibly
optional) hook like 'prepare_build_files', and we leave a standardised
interface for preparing an sdist to be hashed out in a later PR?
