Percentage Field Required on QT for Roles

As a follow up from story 84799 observation 1

Observation #1 - FAST requires the percent to be required when entering all other roles and the user would need to enter that percent when adding/updating roles. The percent should have been required for the Beneficiary Update QT from OOTB but was not and FAST has now made that correction.

Does it make sense then to enhance the system to automatically enter 100% for all other roles except beneficiary? Or does the business want to require the user to enter 100% for all roles for efficiency purposes?
