Maybe the idea of having a short cast iron extension table is to mount a

Not cast iron ones, at least not that I've ever seen or heard of.

While I haven't seen a cast iron extension set up for a router as
original equipment (except on the 3K Powermatic), they're certainly
available aftermarket. For example:
