I wouldn't want this thread to unravel... but it's like going into a 30s repro thread (if one existed) and saying what's the point of adding a cinch and suspender buttons to the jeans, or a 50s thread and asking for a 25cm rise instead. Or looking at the latest TCB 1890s repro and questioning why there's only one pocket...
If the manufacturers are doing a repro, then if what they're copying has wonky-ness then I'd expect them to replicate that. It's just a feature of the time. When the bloke above snips off the extra thread and gets some wear into the jacket, it'll come up looking grand imo.
I'm a sucker for a variety of denim jackets... so happy to embrace the repro features...
I am always taken by how the industry does reinvent and evolve itself with new versions or repeated versions of repeated versions... the new 1942s, the 1890s, the... will it ever end... hopefully not... long live Sufu!
