This is the placeholder based on the recent discussion bitwiseman and I had to standardise the usage for the comparator pattern for the when conditions that are not based on that pattern and might require it.

Tasks

• List of all the when conditions that potentially could use the comparator pattern.
• Explain the migration path as this might imply a breaking change somehow.
• See how to notify users about this particular change.
• Create docs regarding this, if required.
