Yes... but I'm also seeing dogmatism from the opposing camps here in the comments section. The reality is that how flexible your interfaces and abstractions are and their design has to be a part of your original design considerations when building something. It's a bad move to just hand wave away performance concerns because you religiously adhere to some design patterns. It's also a bad move to drop down to using intrinsics for everything from the get-go and thinking you know better than the compiler when it's a codepath that isn't even computationally expensive or a bottleneck a priori.
