Thank you for pointing out the potential risks, Kenny and fantasai.

The use case exists in the original mail[1] but it is not strong, and it looks like the discussion in Japan seem to be "either", so I agree with you, let's NOT take the potential risk.

I've posted this to Japanese ML. As long as we don't see strong objections in a few days, I agree to modify the spec to exclude U+0020 from the transform.

It is potentially a very significant change to implementations to have U+0020 change to U+3000 because this will require that text-transform happens after white space collapsing. Right now implementations can do either: they can transform before or after white space collapsing. So I think we should make sure that this is needed in real-world cases before we make this change. Note that U+3000 has very different behavior from U+0020 -- it is not just a visual change. It has different line-wrapping behavior, it has different justification behavior, and it is not affected by the 'word-spacing' property.
