Yes, but what I meant is uneven CCX. The 4 core parts have 2+2, the 6 core parts have 3+3, the 8 core parts have 4+4. There is no uneven CCX combination like 2+4 for example.

If this applies to multi die solutions like Threadripper, there will be no 10 and 14 core parts as they would require uneven CCX combinations.

If the Epyc lineup is an indication this might be true. Especially since there is no 12 core part for Epyc. Since it has 4 dies you could produce 12 cores by using only 3 cores of each die, but this would require uneven CCX (1+2 or 0+3).
