My company, LiveOps, does the same thing. Every customer impacting issue gets a post-mortem, and some non-customer impacting problems get one.
We have good stability (we hit four 9s recently), but we're always pushing for me. The post-mortem process is very positive and affirming. That's because it's transparent, as it should be.
