Studio - Import raw photos

I never realized this . . . I guess because I’ve mainly used Studio 1 as a LR external editor, which creates and passes a TIFF to Studio. But I’m sure I have opened CR2 files directly before without realizing they are “not supported”.

Why are RAW files are not supported? Virtually every other major photo editing software (Adobe, Skylum, ON1, Phase1, Affinity, Anthropics, and others I’m sure) supports RAW files - why can’t Topaz? I don’t see RAW file support in the “Topaz Studio 2 Roadmap” post either.
