Just like any other taint. If a rmmod can cause the system to lose
integrity, the rmmod could cause a subtle issue that manifests itself into
something more serious and may look unrelated. If you have a bug report
with the rmmod taint, one could ask to try to recreate the bug without
doing rmmod. Or perhaps we have a similar bug reports that all show the
rmmod taint. That would give us an impression that something was removed
and caused the system to lose stability.
