Now full disclosure, I am NOT a fan of Superman. However, this "new power" does nothing to like him more and in fact does the opposite, if that can be done.
Indeed. I don't see this power as very useful. The enemy he was fighting did not die! He survived! I mean, Superman did win because the other guy was just taken out. I can't see this power having a great use, or Superman going "well, time to SUPERFLARE!!" because, if it's in the air, outerspace-he'll die! ~or anywhere there is human life, Superman will kill and destroy it. He may have unleashed this power 'in the wild' but that habitat, and all of the forest's happy little creatures were atomized! Just done in!!!
If you want to add a more human aspect or make a more suseptible Supes, why not just have him run into some strange new Kryptonite (speaking of tropes) that causes him to once again lose his powers, for whatever time you want (yes I agree, the dead locked 24 hours is just stupid)?
Why not, right? Have Clark get 'addicted' to a weakened form of kryptonite that temporarily robs him of his powers. Imagine being able to feel life without having to process it through your super senses? Sure, you can smell all the physical waste in the air, all the sweat, all the humans, but how great (as a human) does that stadium loaded hot dog smell all on it's glorious own?
Also, on the kryptonite thing, I'm very irritated with how writers use it and write on it's affects. In the room, Superman is dying. 4 feet away from it behind lead, Superman is already back on his feet ready to fly through time or something. If I was the writer, the K-radiation would be so lethal that Supes would be near petrified, and sick for hours. Immediate recovery is so cheap, that yeah, it makes Superman have no weakness. The fact he can do anything with it near him makes me mad. It should be a horrible experience!
Does the most powerful being in the DC universe need another power? I mean he used to just be invulnerable. Then they added (in no particular order) flight, super-speed, super-hearing, cold breath, heat vision, telescopic vision, microscopic vision, x-ray vision, vocal manipulation (both impressions and full throwing the voice ventriloquism
), hypnosis, telekinesis and even shape shifting ... plus more. Now of course some of those were during the wonderful Golden Age of comics where everyone was still feeling things out, but seriously, what's next invisibility? Or did he have that too?
Yeah yeah you can leave off those last 5. :p Surprised you didn't include the weird S-shield tarp he threw in Superman II.
