My answer would be yes. Just pushing my holdfasts against the work will secure it without a bash from a mallet.k
This has me wondering also. A holdfast needs to have a bit of slant to hold in the dog hole. There are three points of contact to fix a holdfast. The front of the rod, the back of the rod and being lightly sprung on the work have to all be working in order for the holdfast to hold securely.
If a dog hole is too slick along with a super smooth holdfast it likely will not hold as well. Another problem would be the holdfast being almost the same size as the dog hole. The thicker the top of the bench, the less of a slant for the shaft of the holdfast.
