It is also pointless to even bother re-attaching it.
I went through a Quebec winter, with -40F temperatures and no coolant going through my throttle body.
Car parked outside UNDER the snow, all winter.
Never had a problem, car always started on the first try.
I wouldn't worry about it.

The only reason to reconnect it would be for warranty work. Mazda doesn't like when you start re-routing their cooling pipes.

I suspect it is there to maintain a more consistent temperature of the drive by wire motor. Mazda used engine coolant to maintain a consistent solenoid temperature on the old idle air control valves of previous rotaries. It couldn't hurt to keep the TB coolant hose installed, but it's not going to make a huge difference either way IMO.

I did the simple one minute one and here is a member that did the bypass and seems happy.

I didn't do the bypass and I'm even happier.
What kind of criterion is 'seeming happy'?
Until you put thermocouples before and after the throttlebody, or do a set of related timed runs, you are just guessing, hoping, and looking for another 1% from your butt-dyno.....
This modification accomplishes less than the 'insulating-the-frosty-pipe' one.
Don't get me started.......

Google "throttle ice" or "carburetor ice" if you're interested.

Lose much? This mod does nothing to increase horsepower. It really does nothing for the car at all, except to move coolant so it doesn't go through the TB. I suspect that arghx7 is on the right track that it does something, but so negligible to our understanding that people think it is a good idea. If you really want to know why people think it is a good mod or even a worthwhile one there is a thread about, but still nothing definitive. Honestly there air doesn't sit in there long enough to get hot, you gain nothing except a cool TB and some extra hoses.
That being said I've done this mod, but honestly I have no idea why. I guess to give me something to do for 5 minutes. Maybe it's because when I drive to a friend's house to use their garage I like to be able to take my intake off without burning myself if need be. I have no idea why.
