Back when I was child the weekend roast was usually a leg (or half leg) of lamb.
Once this was cooked, my Mum would place the dish in which it cooked on the gas hob, drain into it the water from any vegetable she had boiled, and then added a little Bisto, to thicken it.
Very unsophistigated for these days, but it worked very well. When mint sauce came in that was always served quite separately.
My DM used to make gravy with veg water, but nowadays I always take whatever joint out to rest for at least 20 minutes, make the gravy in the roasting tin, and shove the tin in the dishwasher to clear the decks a bit. So no veg water yet available. And many people steam the veg now anyway.
