      Description of problem:

      In 4.6, we wanted to drop some default capabilities from the capability set to better secure the platform. However, we didn't want to break existing workloads on upgrade. We came up with a solution where we'd create an MC on upgrade that would add the old default capabilities: https://github.com/openshift/machine-config-operator/pull/2050. However, it seems we never really documented we did that. There were a couple of other similar changes https://github.com/openshift/machine-config-operator/pull/3352 and https://github.com/openshift/machine-config-operator/pull/3563 

      Version-Release number of selected component (if applicable):

       

      How reproducible:

      100%

      Steps to Reproduce:

      1. Check documentation
      2.
      3.
      

      Actual results:

      we don't mention we've done this with machine configs on changes that potentially risk upgrades

      Expected results:

      we should mention them
