I suppose they went 'general' becasue if you stop and look at each and every world, the list would be its own book; I have no doutb they will expand on the origins in later books, but for the moment, I believe the options are wide and different enough to make lots of different regiments.
Worse case, a simple change of an option would work; take the Hive world, change accustomed to crowds to way of the gun (from Inquisitor's handbook) and you got a hive world regiment with a Gunmetal City flavour. No official, but still able to work.
This is very much the case - the Imperium is vast, and you can't expect to see everything covered. The choice of homeworlds/origins in Only War is meant to be a fairly broad representative sample (and one that didn't fall afoul of GW's approvals process).
Modifying them to suit is entirely possible, and doesn't take much for those so inclined - both the Tallarn and Krieg regiments have a different trait to the Death World and Penitent origins that they're based on.
