For sure, it depends on the type of backpacking you're doing and the gear you're taking. Winter brings a whole different set of challenges and I have begun building up a kit for bikepacking and pliers was something no bike multi tool has (that I've seen), but I also wanted it for cooking or handling little things. I use pliers often when sewing occasionally too and there's a few potential repairs that could be assisted with the needle and pliers. Some of it is piece of mind.
It was really hard to find the toolset I wanted when I was looking last year. I really wanted the pliers and a saw and that really limited the options. I mostly wanted pliers for handling little things or hot things as I can be fat fingered. I really wish there was a custom tool option to pick and choose as I rarely need the can opener or a 2nd blade but they're on so many models. I think the Hercules was pretty close but they were not in stock anywhere, the price was much steeper the the S52 and it was pricey. I love the tool selector search feature on victorinox's website, that helped a lot.
In reality, I feel like I have 4 or 5 (probably more) backpacking/camping/bikepacking loadouts made up with different stoves, tools, and comfort items depending on what I'm doing. If I'm with the family, I'm the mule so I over-pack like crazy and luckily we don't hike too far. Luckily, I don't have to pack any toys because every stick, stone, and insect is a new toy. We don't travel fast.
