There isn't much of a plan. https://github.com/python/cpython/pull/23896 makes the optimizer respect PEP 626 w.r.t. jumps-to-jumps. From the point of view of optimization, there is nothing special about jumps-to-jumps. Any optimization that offers a speed up is good, regardless of which language feature it relates to. To be honest, bytecode optimizations are going to win us a few percent max, whereas speeding up the interpreter could gain us 50-100%. So I'm not going to worry about trivial differences.
