While I'm not competent to comment on the other points, I would venture
to suggest that, in order to accomodate a future Decimal type (and
DecimalFloatingPoint protocol), a BinaryFloatLiteralConvertible may be a
necessary subset of FloatLiteralConvertible - as some literals don't
have a lossless binary representation, etc.
