LGTM
Sorry I didn't see this problem, and thanks for fixing it!
If you have any perf data that you can share, it would be good to include that here or in the commit message. I'm curious if this change recovers all of the compile-time perf or if walking the icmp users is also expensive (although I'm not sure how to make that any faster).
