You don't like it? Don't do it. You want us to join you in not liking it? Show us some data that proves it's unsafe. Obviously, you shouldn't do this while under a deco obligation, but if you're within your NDL, then why not? Don't race to the surface. Don't spend any more time than you need while there. Descend back to the bottom and continue your dive on the correct route. You'll probably create far more bubbles exerting yourself trying to swim back to the boat against a current because you failed to do a commando peak.
Just because you don't like, teach or do a practice doesn't make it unsafe or even poor.
First, I don't really care how others dive, I am not a part of the SCUBA police force. My point to the OP was that as he was frustrated/upset to the point where he was counseling others about their dive practices he was employing a practice that is not necessarily the best either.
Second, where is your citation that shows this is a good practice to do?
The risk of a boat strike is increase as you do this, and so is the risk of micro-bubble formation...last I checked most training agencies recommend against a sawtooth dive profile. Heading to the surface and re-descending kinda creates that higher risk sawtooth scenario that can contribute to a DCS hit.
The problem with the "commando peak" is that I have seen divers and read about divers who do it repeatedly during a dive because they either do not trust their navigation skills or their navigation skills are generally weak. Each time one pops to the surface to see where they are going and re-descending they are increasing their overall risk. Your implication that one might exert themself swimming against a current that they would otherwise not need to is just an example of poor dive planning and/or navigation.
In the context of which is best, creating bubbles due to unnecessary exertion against a current, or creating bubbles due to bouncing to the surface....neither is best...what is best is organizing and executing a better dive, what is best is improving navigation, what is best is reducing as much as possible the chance of injury, illness, and death due to poor practices. What is best is not advocating a poor practice because we have thus far been unaffected negatively by it.
