Physically, it should make little difference - symmetry tells us that at the connection point, no potential difference between left and right side can exist, and without potential, no current.

It's fairly common practice to build especially larger yagi-uda with the elements simply screwed into, welded onto or crimped into the boom for stability reasons.
