The main site does it, why not the meta site?
This was done as part of Stack Exchange's standardised site design rollout. Both main and meta-site motherships will now fire their lazors on page load, after a short delay.
For now, this isn't a near-term goal. Jin is still our only designer and he's kinda... being torn apart by us dragging him to deal with everything, every other thing, and everything on top of that. It apparently isn't a trivial process for him to setup weaponry here on Meta, so it'll have to wait until the necessary time investment slot exists as usable time that doesn't take away from other pursuits. It may be on his plate far down the road.
