True that. But it isn't in any way outside the general Trek parameters that a fairly low traffic load would already put thousands at risk: individual transports supposedly carry that many people already. And "Errand of Mercy" consistently suggests that the ownership of a Class M rock is strategically significant, completely regardless of what sort of industry, culture or lichen may be growing on that rock.
"Armageddon" doesn't stand out in this respect, then - nor in the respect of giving very thin exposition at the beginning and then never really returning to it. Which IMHO makes speculation all the more fun, as the cues and limitations really come from elsewhere in Trek: the works of unrelated, often disagreeing authors must be rather brutally meshed together and then molded to all-new shapes to provide the answers.
