I'm certain that there is a valid reason. Nevertheless, it feels like a footgun and that footgun will find itself embedded somewhere deep in code I didn't write. If it can explode in my face despite careful testing, I'm not really happy about that perspective. I'm sure that there is a tradeoff somewhere and that you gain something by allowing this in the library. But I'm strongly on the side of developers for whom reliability has a very high priority.
