Some people have asked for failed speculative execution to be truly side-effect free. Like a transaction buffer that speculative execution can manipulate without evicting or impacting L1/L2 until the speculation is committed. I don't really think this is a great use of transistors, and is why CPUs will probably never do it, but theoretically possible maybe.
