This one for sure does add some process, and the real impact on security is not this great.
I mean, it can help, but mostly if phpbb is not up to date or if register global is on, and you should not run an outdated script and never use the register global option. It's always possible to do it, better for security and performances.
Now I am not sure about it, but it's as well possible that the mods does as well limit the SQL load, a bit too much
phpBB3 is better designed, but as well doing zillion more things. In the end it should still be less server resources consuming.
