Just to make sure I understand you correctly: you want tuning flag (set for skylake/zen/haswell) and no command line flags?
I'm worried that this will cause some confusion, e.g .user requests  -mprefer-vector-width=128, but sees ymm (256-bit) generated and files a bug, etc.
It is also easier to evaluate changes that are enabled by individual flags.
