I would agree with statements form Joel earlier with respect to cases where early vendor support may have influenced some network zones (inside a given AS) to support a different IGP (his case of OSPFv3 for devices which lacked IS-IS support is one I did face a few years back as well in the DC with respect to Load balancing and Firewall devices).

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. Mark.
