Required field overrides for forms that have currency data types do not work. For example, on the Opportunity Add Form, change Expected ask amount to required. When you add a new opportunity now, the default $0.00 placeholder value. "$0.00" should not be an actual, populated value in the form, but instead an HTML placeholder.

As a result, we have to maintain a series of data quality queries in order to ensure that organizationally required currency fields don't have values of $0.00.
