It is safe, but these are the remaining standard deviation paths:
The common derivation path which is usually used is m/x'/0'/0' not m/x'/0'/0'/0/0.
For example, m/44'/0'/0' is derivation path used for deriving legacy addresses and refers to the whole wallet while m/44'/0'/0'/0/0 refers to the first legacy receiving address and m/44'/0'/0'/1/0 refers to the first legacy change address.
