After looking at the pseudos a bit more, I really prefer to commit this.

Of course, if we have empirical evidence that this misses cases, I'm open to moving to anything that works better - be it a post-RA pass, or Pseudos.
Dave, feel free to provide such empirical evidence in the form of PRs assigned to me. :-)
