Camps which need Widescan are rare and decidedly unpopular. Accuracy is nice, but how often do you see combinations like DRG/RNG or even SAM/RNG in the Lv.20's where /RNG really stands out? That said, if THF main job players tell me /RNG is a strong support job which every career THF should have and list some concrete examples, I guess I can change my mind.

You don't often see those combinations because most people don't hear about them. /RNG is awesome at low levels, but it's hard to talk about what works at low levels because you're always interrupted by someone talking about what works at high levels.

I'd say that /RNG ranks among the best low-level subs for THF so long as THF is making use of its native Marksmanship skill. It's also nice to have the extra acc when you're using Sword. But it's certainly not a must have. No one cares that much how good your sub is 10-30. Moreover, many players would rather go /NIN from 20-33 to skill dagger in off-hand. And /WAR starts to take off as a sub 30+. So you could easily get by never touching /RNG. I think you'd be missing out on something, but it's definitely not a must-have. Particularly as from 60 on it'll become increasingly difficult to justify subbing anything other than /NIN or /WAR.

Also, to forestall the inevitable "/NIN is better" response on RDM/PLD, Pter doesn't have NIN to 37 yet, but even compared to /NIN fully leveled, /PLD does provide somewhat stronger melee (Vorpal Blade, anyone?) alongside its survivability. So it provides something of a balance between the offerings of /NIN and /WAR in this context.
