That's totally fair. Flip side arguing "we shouldn't do this because people who only care about immediate performance don't want them" feels like it is ignoring some percent of people who may not feel that way, or even the possibility of using it as a way to bring more people to systems level programming but are not up to making the leap Rust currently requires (which will hopefully become less of an issue as they work on this year's roadmap, but I would certainly argue still exists right now and we won't know how successful their efforts REALLY are until they are all in place).

When IBM researched RISC in the mid-70s, on the IBM 801 minicomputer, they decided to use a subset of PL/I as their mostly safe system programming language. They implemented a botstraped optimizing compiler for it, making use of an intermediate language with multiple optimization passes. http://rsim.cs.illinois.edu/arch/qual_papers/compilers/auslander82.pdf http://rsim.cs.illinois.edu/arch/qual_papers/compilers/ausla... It was like having LLVM in the 70's and is only one example of the research on optimizing compilers since FORTRAN was created.
