While non-evictable pods should never be evicted, they should still be
considered when calculating PodAntiAffinity violations. For example, you
may have an evictable pod that should not be running next to a system-critical
static pod. We currently filter IsEvictable before checking for Affinity violations,
so this case would not be caught.
