Could it be the change on service interval had more to do with environmental concern rather than the longevity of the engine (change more = more waste oil)? Or because of the lubricant and fuel technology advancement?
As far as I know, operating the CB1100 in hot, dusty and dirty area would have the the oil cook up pretty bad even before 5000km. Most of modern bike sold in my country are listing 10k km service interval, but non of the dealer ever recommend it. Its dusty, high humidity, raining all the time, and always high temperature (>35C) here. High reving engine's oil rarely last more than 5k km before the engine oil drop below the minimum line. And anything used more than 3000 km and you'll start to feel the engine smoothness being affected.
Nonetheless, with green supporter pushing for less and less carbon burning engine, the longevity of the engine is no longer an important factor. Look at all the targeted No fossil fuel vehicle timeline..
