Right, you can still take them and opt not to use them. I just don't see the benefit in taking them at 10pts/model. You lose your ability to run, sweep, or overwatch. Why not just not take them and give them something more useful like black sun filters, let them snap fire, and use marker lights to up the BS from the snap fire?
Can you do that?! Move 6", allocate marker hits to raise BS, then snap fire at TL BS 1+ marker hits? If you can (and I know the codex, faq, and rule book don't say you can't. It's not even addressed!) then you still have a chance to move 6", snap fire at BS + marker hits, assault/overwatch/sweeping advance!
IF that's the case, there will be 9 Broadside lists everywhere...
