The mutex requirements force try_lock to be noexcept(true). However, where they are used by the generic algorithms, those relax this requirement and say that try_lock may throw. This means the requirement is too stringent, also a non-throwing try_lock does not allow for a diagnostic such as system_error that lock() will give us.
