To be honest - thats one of the issues that is of rather low concern to me. There are many other battlefields where I see much bigger issues.
I am no fan of ready/stow, but also not an enemy.
That means - as long as its an official rule, it will be played RAW.
Dropping a sword is for me rarely a reason for damage to the weapon...dropping a plasma gun or bolter...might be a different issue, if it happens too often (which I don't track but do rather randomly).
