Someone who wants to dig through spec change history to find one will need
to do it, then.

It does seem fundamentally odd to have values quantized to floats in a
language that doesn't actually have them, if it results in "(x = y) == y"
being false.

The only case I've seen where floats are still useful is when you have big
arrays of them, like floating-point textures and 3d models.  What's the
point of using them in DOM APIs?  I doubt it would actually help a platform
without hardware doubles...
