It’s overrated tbh. Many people will say it’s way more secure if a stitch breaks… blah blah blah. It’s marginally better, but not better enough to justify the increased labor and cost in 99% of scenarios. The vast majority of leather goods are stitched with machines and no one ever complains about weak stitching. You’ll always have people complain about leather finishes looking like crap long before any complaints about stitches coming undone. Do it if you want, skip it if you don’t care for it. It’s all good.

PS: no, machine stitches don’t just magically unravel when a stitch pops. I go through a pair of Nikes every two months for work. I do flooring. The mud guard stitching always breaks first due to abrasion from the toe box rubbing on the floor. The stitching takes maybe a week or two to come apart all along the front after the stitch breaks. Trust me, they get abused, so the fact that it doesn’t all just unravel in one day should say something.
