IMO the reason they are not permitted in some areas is the same with electrical. Crafts have persuaded the locals/state to outlaw them so they will get more work. Nothing to do with if they really are a problem.
I can answer your post with your own words...
You really need to separate your opinions and personal preferences with real factual data and state as such when you post.
In reality saddle valves are not allowed in some areas because they are not reliable long term. Best practice is to install a T and a real shutoff valve. I always recommend anyone with a saddle valve should cut it out and install the proper hookup.
This is what the seasoned plumber I used to work with (who took a retail job after retirement, for something to do) used to say, as well. He'd see someone with a saddle valve in hand and ask them if they had a pipe cutter and torch; if they did, he'd put the right parts in their hand, which were often cheaper than the saddle.
We're talking about a plumber with over 50 years of experience and no profit motive (he wasn't being paid to install the parts and the correct parts were cheaper; he was also retired and worked this shitty retail job for kicks), if he said it was the right way to do it, it was. Let's see if Jack can figure out why that might be the case.
If it comes down to it, I can just explain it, Physics 101 style, like my former coworker explained it to me. If there's still argument, we'll have found our problem.
