As an administrator I would like to hide the error message when removing issue deletion rights for agents

The configuration should allow for the removal of issue deletion rights from the permission scheme without showing a message to the system users:

"This service desk project may not work as expected.
View details and repair the problem"

In most cases we do not want agents to have the ability to delete issues as a disgruntled employee (there is a lot of turnover in service desks, for a reason - it can be a tough job) could in essence wipe off an entire service desk's history.
