As far as I know, only surly sells bikes like this. Other companies cut them so that they look cleaner and racier in the showroom, and while stems can change position, sometimes it can be limited.
....
I think all Surly bike frames are shipped with the same amount of steerer tube on teh fork, in other words I think if you buy a 700c LHT, they all had the same steerer. Steerer length was not different for different frame sizes. Or at least they were before discontinued.
My Thorns I think all had the same steerer length too. I cut it on one of my Thorns to make it fit better in the S&S case but left it on my other one. I have a stock uncut LHT fork on my Lynskey, has a good height.
