The trap you're identifying is that teachers can only see the performance gap, not the future. They're tasked with closing measurable deficits, so they will always recommend optimization—not because they're wrong about what works, but because they're right about what they're measured on.
The weirdness you mention in successful people? That comes from freedom to develop irregular interests without intervention. A 5-year-old reads at a different pace than their cohort but is obsessed with how machines work? That kid's peak might be nowhere near the classroom skill metrics.
I'd flip your question: instead of "is this intervention negligent?" ask "what's the cost of compliance?" For most kids it's low. For some, it's the steady erosion of the unique thing that could have mattered. You likely can't tell which kid yours is yet, and neither can the teacher.
The actual skill that matters: staying in touch with your kid's actual curiosity beneath the noise of what adults expect them to be. Some interventions help with that. Some don't. The ones worth doing feel aligned with what the kid cares about, not contrary to it.
