The question for me is whether you can retire the FE issue with a BE dispatch, and if so pull in another FE issue.
Almost certainly yes. It's supposed to be fully out-of-order, which means it should have a fully functional scheduler in between the FE & BE.
Not to mention, given modern memory latencies (vs. clock speed), letting the FE run ahead is important for performance.
