On Linux, ptrace permissions can be restricted [0] and some distributions do this by default. Whether this provides any meaningful security is questionable unless you pair it with filesystem isolation to prevent malicious programs from modifying config files / bashrc / etc. Meanwhile it does make legit uses of ptrace more annoying.
