Performance degradation after enabling RCAC

Performance degradation and difference in behavior of access plan on stored procedure query after enabling RCAC - column masking for a column which is part of select condition.

The query access plan without RCAC is scanning only the table (Table A) and the query plan with RCAC its going for entire view scan/filter instead of single table (Table A) it scan/filter for all the tables in view.

By this additional scan/filter performance of the select query is getting impacted.As this is design and expected behavior of RCAC,if the security feature creates the performance degradation for union all scenarios. How the vendors can compromise the performance impact by using the security features.

Please consider this request and have enhancement for this performance impact.
