Remove calculated fields from lists if they aren't needed

Even if a field on page is hidden by setting the Visible property, the data behind the field will still be loaded.
Remove calculated fields from lists if they aren't needed, especially on larger tables. Setting the field's Enabled or Visible properties to false isn't enough.

A new rule to warn against FlowFields on pages of type List, where the property Enabled and/or Visible is set to false.

If out-of-the-box the field isn't shown on the page, don't place it on the page, where the field can be added though the add existing table fields to optimize your pages feature.

Based on Henrik Helgesen on Bluesky I think it's best to close this idea and not create a rule for this.
