It's a non issue in uncontested auctions, but you're guessing completely an awful lot of the time as soon as the next hand WJOs aggressively (we do this systemically on 4 card suits), and have plenty of occasions where cold games are passed out and collecting 50s because neither hand can double as they hold 4 trumps, and nobody knows what the real shapes are. Also I have a large collection of hands where big minor suit fits never get found in similar circumstances after partner raises the WJO.
