I'm struggling to understand why building a sdist in flit should need
a VCS. It bothers me that I'm missing something important about how
backends will work, that explains why (for example) you can't create a
sdist from an export of a VCS branch (i.e., without the VCS metadata).

Can you provide a pointer to the docs on flit's "build a sdist"
command, that explains the limitations? (I gather that this is in
development, so a pointer to the doc files in VCS is fine).
