Should CPython be optimized for 1, 2, 3, or 4 or more cores? The answer to this is obviously changing. I will soon replace a single core with a 4/6 core machine,

I don't think you can answer that just by considering the average number of cores in a CPU. Even if my CPU has 4 cores, most of the time the Python code I run on it isn't going to take advantage of more than one of them, simply because it's not written to be multi-threaded.

I would not like to be in a position where I have to use some number of cores in order to get reasonable performance from my Python code.
