Also, router CPU's were much slower then than they are now.

The IGP's have gotten a little more complex also, but by-and-large, are
still the same if you don't do "fancy things". So there would be a
certain amount of increase in scale that an IGP domain would support,
perhaps, regardless of which IGP is chosen.
