Neat, but it seems like a "good enough" solution shows up near the end of the video right next to the new solution: cardboard spools. But hey, the more options the better, so good on them for offering this.
My experience with cardboard spools is that they deform a lot more easily than plastic. This is a problem for me as I vacuum seal my spools for storage since I live in a swampy area. Once deformed, they don't roll as smoothly (and they already don't roll as smoothly as plastic even without deformation). They also shed a lot of dust.
I prefer not throwing away plastic spools, so I still mostly prefer cardboard, but a solution like this one is the sweet spot IMHO.
Print a plastic hub and insert before you vacuumed seal, easy to reuse and makes the cardboard rolls easy
To be fair, never had a problem with cardboard spools so far. But I also have a reusable spool from Sunlu I'm using for most of my "normal" filament where color doesn't matter.
Nice idea
Definitely better than the usual full plastic spool, but IMHO a step back from "true" masterspool refills. I've already printed my MS spools, switching in a new refill is easy enough, and I never bother to store an already opened refill without a spool since I store all of my filament in a drybox anyway.

Not liking them switching to plastic bags.
With cardboard boxes, you can stack them on the shelf. With these bags, it gets messy and you can't see what filament is in which bag.
