Meh about it. How does one put Sandman or Hydroman in a rear-naked choke, anyway? And is Spider-Man really going to bother with getting into a proper right front stance before delivering a double right roundhouse kick to the Green Goblin? He has done fine without them all these years, I think the need for them goes away with superpowers.
Perfect humility dispenses with modesty.
In the cases of people like Iron Man and Doctor Strange, learning martial arts also compensates well for when Tony cannot access his armor or Strange cannot access his magic or worse, Tony's going up against a foe with more powerful armor than his or Strange is up against a superior magic user or more powerful magical entity. In that same vein, if two people with similar strength, speed, and durability go up against each other, the winner is usually the more skilled as opposed to the more powerful, which is why Hulk can be beaten at least some of the time if he's not tapping into his Green Scar persona, who is a highly skilled strategist, tactician, and fighter in addition to being the most powerful entity in the universe if you're talking raw physical power. In the end, the point is that knowing what the hell you're doing can give you a greater edge than superpowers alone, which is what martial arts ultimately is about; anybody can figure out how to fight, but martial arts teaches discipline, self-control, and precision, which makes you a lot more effective than striking out on pure instinct will.
Back in black, the hunter is ready to claim his prey.
It's not wrong, but it's not an idea I particularly care for.
Life looks better in black and white.
From an in-story perspective, sure, he should develop new skills that synergize well with his superpowers and existing abilities. But from an out-of-story perspective, it's sort of pointless for the reasons already mentioned. Now he can beat Elektra 10 seconds faster than he could before. Who cares? From a storytelling perspective, I think it's more important for superheroes to be less uber than more. They shouldn't be able to beat everyone in the world.
Just like when Slott had Jennifer Walters work out so that she could be even stronger as She-Hulk, it was a clever way for Spidey to deal with a problem, but it wouldn't break my heart if he lost those skills from disuse. Besides, the guy has enough on his plate without having to train x hours a day with Shang-Chi when he doesn't really need to.
