Yeah I know they don't tend to want to just hand you over low-level access, like an `asm(...)` statement in C (or maybe like instrinsics). But pragmas tend to be a bit less explicitly "mess it up". Like in the case we're talking about, a loop performs slightly worse by default and it might be nice to nudge the compiler into the right direction. Just as go isn't "messing [it] up" by selecting a slightly suboptimal instruction here, you're not "messing [it] up" if you annotate a loop slightly incorrectly.
