You're describing cut-through switching [1]. Because of its disadvantage, it is usually limited to uses that require pure performance, such as HFT (High Frequency Trading). Traditional store-and-forward switching is still commonly used (or some hybrid approach). "The advantage of this technique is speed; the disadvantage is that even frames with integrity problems are forwarded. Because of this disadvantage, cut-through switches were limited to specific positions within the network that required pure performance, and typically they were not tasked with performing extended functionality (core)."
