I am with you, definitively, but the point is absolutely reasonable with hubs spoked 1:1-left:right. What do you think about tension behaviour in wheels spoked 1:2-left:right (typically 24 spokes hub equipped)? My idea, truly basic and unexperienced, is to put heavier spokes on the NDS, given that the 1:2 spokes system increases left tension of 22% (source: well known Sheldon Brown website), but offers less material to oppose to the DS, with the risk to have spokes elongations (upon dynamic forces) only on the NDS? In theory, elongation is proportional to to the spoke section. Possible solution: on NDS butted in order to keep constant tension on nipples, but heavier not to elongate too much.
I really care about your opinion, before to start my next wheel project.

Spokes "elongating too much" isn't a thing, unless you're using extremely skinny spokes on the drive side of a conventional real wheel. You'd have to deliberately make it happen.
