TIL: lerp being A*(1-t)+B*t, if you lerp between the same value, say A=50 and B=50, you'll get a value that isn't 50, for some values of t. (floats) Kinda obvious in hindsight but surprised I never hit it before. I had to put in a special case for lerp. If (A==B) return A

That’s the whole point. A core lerp() should not assume real-time or not. You, in your own application, can write a wrapper that makes some aggressive checks. Then you use that everywhere in your project.
At that point, you have the context to know what sort of trade offs can be made.
