Do I need a custom 128-bit UUID if I delete one or more Characteristic from an Adopted Service

Do I need a custom 128-bit UUID if I delete one or more Characteristic from an Adopted Service I do not modify the remaining Characteristics

For instance: Sniffing with Master Control Panel \nRF5_SDK_13.0.0_04a0bfd\examples\ble_peripheral\ble_app_hrs\pca10040\s132\

One of the services used is Generic Access, but only three (3) of the 5 Characteristics are used. But then a Characteristic Central Address Resolution UUID 0x2AA6 shows up under the Service

Should not this then be a Custom Service, with a 128 bit UUID? Device Name UUID 0x2A00 Appearance UUID 0x2A01 Peripheral Preferred Connection Parameters UUID 0x2A04 Central Address Resolution UUID 0x2AA6

Bluetooth SIG indicates that:

"Yes, you will need a 128-bit UUID if you delete one or more Characteristics from an Adopted Service. Please note that a product that does not support all the characteristics of an adopted service may have difficulty qualifying to that service."
