BuddyPress.org

Hello,
i want to prevent ‘updated_profile’ and ‘new_member’ activity types, to appear in Activity Stream.
Searching in the core of Buddypress i figured out that removing the following hooks, would do the job:

remove_action( 'xprofile_updated_profile', 'bp_xprofile_updated_profile_activity');
remove_action( 'bp_core_activated_user', 'bp_core_new_user_activity' );

Is there any drawback, missing point or some hidden effect with these methods?

thank you in advance.
