Generally, when I optimize at that level, I have a window open on the assembler output of the compiler and I go back and forth on the source code until I get the shape of the assembler I need. Having compiler messages wouldn't be very helpful.
Not everyone has time/knowledge for checking the ASM at every recompile. Personally I wouldn't be able to do something like this that much often, and yet I'd love to know that something is not working ASAP.
Code changes, and it changes a lot during development. Having a way to make sure that one or more functions stay inlined is handy to have. If such a pragma doesn't guarantee inlining, that means we will have no way to check it quickly. Sometimes fail fast is really the best choice.
