@ safetypee.
if you are going to select it, then use it all.
Then how do you comply with Notes
"1.2.3 REVERSE THRUST
More than idle reverse shall not be used except for safety reasons or if necessitated to comply with ATC reuest" at LSGG, or
"1.2.2. REVERSE THRUST
Avoid use of reverse thrust after landing between 2330-0600LT except for safety reasons" at EGKK etc. etc.
Is that the real reason for the safety pee?
