An 18-55 FF lens would be quite large and VERY expensive if any good.I'm not sure this continuum will continue to exist.
The EOS 850D is priced $750
The EOS RP is priced $900
The EOS 90D is priced at $1,200
The EOS R is priced at $1,800
So the existence of the continuum depends on lenses, e.g. the customer saving on something like the trio of kit lenses (10-18mm, 18-55mm, 55-250mm).
I doubt Canon can make a 10-~20mm lens that would be both <$500 and give sufficiently good image quality for anyone with a FF camera to want to keep it. Actually, if the 18-55mm did a reasonable job on FF, the customer could dump the 10-18mm, so maybe Canon can pull off a crop RF rebel with a couple of lenses.
