Riding a '38 Autocycle Deluxe
My experience has been interlacing the last cross makes the wheel a little less prone to going out-of-true with use on most paved roads. It's not a large difference. Most vintage wheels were not interlaced, and they function just fine when subjected to normal riding conditions. It is not mandatory if the wheel is otherwise built up correctly. More important are correct spoke length, reasonable spoke tension, condition of the rims, and use of proper spokes/spoke washers/etc. Don't sweat the interlace or not question if you can otherwise build up a wheel competently.
The beauty of cross-4 tangential spoking is that it reduces the effects of variations in hub flange diameter on spoke length. It makes it somewhat easier to get an accurate spoke length measurement. But that is a convenience thing more than a strength thing.
