It might be because I have so many other ways to go about it, but I just don't see the "need" for the huge 52" rail set-ups. 30" is more than enough to cut a 4' sheet of plywood in half. Other than that, I would use a track saw. Cross-cutting full sheets is pretty much a no-go, so again, track saw.
Dust collection from a contractors saw is minimal in the best circumstances, track saws are far better there too.
This is a choice of moving the "correct object". When the panels are large, move the smaller saw.
When the pieces are small, move them over a table saw.
It works the same with routers. You move the router over big parts. You bring small parts to a router table because they are difficult to hold onto and move the router.
Routers for table use and router tables in general, are a personal thing. Some guys like them attached to the saw wing, others don't. I'm a don't on this, but it may be different if I had a space problem.
When they share space, order of operations is a much bigger thing, especially if they share the fence.
I keep mine on a separate table, even going as far as having two. I generally keep one ready to cut rabbets with a fence and fence-mounted dust collection. The other has a flush-trim bit and gets used without the fence, having under-table dust collection.
