I'm fine not to allow multiple custom transforms together, but I'd like it be usable between predefined and custom, and between casing and full-width.

What you're proposing looks like not to allow them, and @text-transform doesn't help in that regard at all if I understand your wiki correctly.

I understand the order is best at this point, but we could take either, and add the other order in future if desired. Prohibiting doesn't still make sense to me.

I don't want to prohibit combinations. I say we may not need two different mechanisms for combining.

When the text-transform property is used to combine two transforms, the order in which they are applied is not under author control. It is predefined for predefined transforms. Without knowing what all transforms that are being combined are, we cannot specify in which order it is best to apply them. Because of that, I don't think the combination mechanism of the text-transform property is adequate to combine predefined transforms with custom transforms, or custom transforms together.

Since the combination mechanism in @text-transform is able to deal with all cases, thanks to leaving the order under author control, I propose that this should be the only mechanism we keep.
