Starting from an empty whitelist and waiting for people to scream
with valid use cases would automatically give us the single pass to
identify the set of essential ones that users must be able to pass,
no?

Of course, the screamed proposal to add something to whitelist must
be vetted (i.e. "yeah, we can see passing X in _your_ usecase might
be useful, but here are downsides (e.g. security implications) of
allowing X in other usecases").  And we might even find that it is
insufficient safety to allow/disallow per variable name during that
discussion, in which case choice between whitelist and blacklist
becomes moot.
