The current version of LDD contains the 4460 with closed hollow stud!
It seems that there are no internal ribs or something else. Please we need this confirmed on a real part.
Unfortunately I'm not at home tonight, but I'll have a look into my collection tomorrow.
I think, we can trust that to versions exist. I own the completely opened stud and on BL there is a picture of the hollow stud version. Now we only need to know the underside differences...

I checked my parts. most of them were of fully open type, but I finally found hollow stud version. Except for that difference, they seem completely identical.
I'll improve the old file and create the new one tonight...
