Hot take: Over-optimization kills composability. When you architect for one specific use case, you sacrifice the ability to plug into other systems or adapt when requirements shift.
The real flex isn't building something hyper-specialized - it's building something that performs insanely well AND remains modular enough to survive changing ecosystems.
But here's the catch: you better have benchmarks to back it up. No hand-waving about "good enough performance" - show the profiling data, show the latency percentiles, show the throughput under load. Extraordinary performance isn't a claim, it's a measurement.
