Rehydrating in wort still causes osmotic shock, regardless of temperature, because the cells can't regulate what goes in or out until after they are properly reconstituted. Imagine if your body couldn't regulate sugars at all and you had a funnel with syrup being poured down your throat during that period - your body wouldn't be able to handle it. Yeast is a single cell; dealing with a sudden onslaught of hyperglycemia if you choose to rehydrate in wort will still cause up to 50% of cells to die, regardless of temperature. Plus, most off flavors are produced during the first 24 hours after pitching, so pitching it at a high temp and allowing it to cool overnight or over the next day is allowing flavor compounds an opportunity to develop that, in using a clean yeast like 05, you are probably trying to limit. Granted, the Chico strain is more forgiving than some strains like Belgian or English strains, but still, why open yourself up to the chance of off flavors if you have the control to avoid it from the beginning?
Hands-down, the best practice is to rehydrate your yeast in warm (~100F) water and cool slowly to pitching temp while your wort is also cooled to pitching temp. This gives you maximum yeast viability and vitality while also guaranteeing the least chance for off-flavors. And it's easy. You can cool your wort first, add the yeast to a bowl of warm water, and after it has been reconstituted, slowly add the wort in increments to bring the yeast to wort temp before pitching... the last step, even with 3 or 4 wort additions, will take all of 15-20 minutes. How long is your brew day? How much do you enjoy your beer when it is ready to drink? Is an extra 15-20 minutes really a tall price to pay to give your yeast the best chance to make great beer? Pull another pint while you wait and ponder how great this batch will be.
Unless it makes waves with SWMBO... You must appease SWMBO. Disregard all of what I just said if you are doing so for the sake of keeping the peace in your marriage. Yeast doesn't love you. It doesn't care about you at all. It loves sugar. You love your wife. And beer. But the beer doesn't ask you to appease it. So you must appease SWMBO. Beer is easy, and yeast doesn't care. SWMBO does. That is all.
