Then declarer would by necessity learn to ignore tells, and if he chooses to act on tells, he does so knowing all the risks involved.
The current rules are absolute nonsense. The safest legal way to follow them would be to take 60s for *all* actions, including passing as opener on a 0 count and following suit with a singleton.
Do defenders get any adjustment in this situation? Declarer leads up to KJx in dummy, and once LHO has played low, will go into a tank for a minute before calling for a card. If he then guesses right, all the commentators and bridge world will be all praises for his "table sense".
