I was hesitated having a new debug level for just RedfishPkg, until I realized not only RedfishPkg but also ManageabilityPKg and edk2-redfish-client need a specific debug level. The scope look to me big enough to create a new individual debug level due to lot of debug information for those modules and people don’t want to see VERBOSE is enabled on all modules just because PcdDebugPrintErrorLevel is overwritten in platform DSC in most of platform development practices. There are many modules and multiple layers of driver stack in the above packages, especially to the upcoming package under edk2-redfish-client repo. It seems to me it would be pesky to developers for turning on VERBOSE on certain modules one by one.
