Does part 6222 always have an x axle hole, or could it also have a + axle hole?

6222 Brick, Round 4 x 4 with 4 Side Pin Holes and Center Axle Hole Parts: Brick, Round
I checked a bunch of them that I have, and I only found two types of axle holes:
a perfect '+' axle hole and what I call a thick 'x' axle hole.
These two types are so similar, and I did not find a thin 'x' axle hole
like [p=32064b]
If it has both, does it need to be split into 2 variants (6222a/6222b)?
The site does not look favorably on these kinds of splits, so I am not sure if
it would even be approved. In fact, there have been discussions in the past to
merge different axle hole entries as they provide no different functionality.
And as I stated above, the thick 'x' axle hole and '+' axle hole
are just too similar.
