But isn't the whole point with X/3 to AVOID conversion? So everything
is embedded "as is" with information on colorspace/profile. And then
there is only ONE conversion done in the RIP?

If you supply everything converted to the same (CMYK) profile, you
don't (as far as I understand) need X/3 but can supply a 1.5 PDF

Or is there anything in X/3 (other than mixing colorspaces) that is
not available in PDF 1.5?

Everything I have read about X/3 says that "if you don't know what you
are doing, don't use X/3".
