Why don’t low light cameras just use bigger sensors?

This might be a stupid question, but I have just been interested in low light photography and how these new cameras have clean ultra high ISO and such. Why don’t these low light cameras use bigger sensors too? From crop sensor to full frame you gain a full stop of light. Why not just make the sensor even bigger and collect even more photons?
