I noticed the 419mm chainstay spec too right away, and wondered why Surly didn't make them longer.
It's 419 with derailleur drivetrain only. With an IGH you could extend it to a maximum of perhaps 450mm by locating the axle at rear of dropout. The Troll probably makes sense as a tourer if you're building around a Rohloff hub with disc brake. Perhaps this was an intentional design decision by Surly to avoid eroding sales of the popular LHT.
The less costly LHT frameset is the better choice for a derailleur drivetrain, although I wouldn't mind a LHT with troll-like (actually, waterford or comotion would be better) chainstay disc brake mount and disc only fork.
