Should conformed schema show also columns produced by std&conf?

## Background
@dk1844 implemented a feature (#763) to view schema after conformance.
This Issue is created for possible discussion and can be transformed later into a feature request
This can be solved during the audit phase

## Question
Should schema after conformance include metadata columns that are added after std&conf?

On one hand, they are not columns produced by the conformance rules
On the other hand, it is conformed schema and that might be viewed as the whole process
