Hope so. Love it. Fuck plastic where it's not needed.

I'm noticing more brands embracing cardboard spools and I'm for it
They're easier to recycle
My only issue is when they're full they squeak on my filament holder during printing, but I'm planning to fix that... Eventually.
If companies that still used plastic spools are starting to switch to cardboard, I think that's a good thing. Not only is it easier to recycle, but probably also lighter (your typical 1kg filament spool weighs around 200-300g), so the bulk should save some fuel for transportation.
Though I personally prefer using no spool at all (during shipping) 😉 Wherever possible I buy Masterspool refills.
the spool is frequently included in the weight of the roll, so you're getting 1kg either way. you get more plastic for printing, though.
Uh, that would be deceiving marketing, a 1kg spool should contain 1kg of filament...
But hey, maybe my view on this is a bit warped because I only buy filament from reputable brands (and usually from their own store) and not from marketplaces like "big A" where hundreds of sellers battle to be the cheapest.
It’s not a “reputable” thing … it’s a process thing. Scales don’t get zeroed every time a fresh spool is loaded. Doing so adds complexity.
It’s pretty common for consumer goods to include the mass of packaging when the product is sold by mass across most industries.
I have had cardboard spools for a while. I am on the fence. They are much easier to recycle (no matter how many 1million and 1 uses for plastic spools exist). however they creak horribly on my spool holder, and are much larger than most of the similar weight poly spools i have, so i had to create bespoke spool holders for all 3 printers i have!
They don't seem to work very well with the AMS system from Bambu. Good news is can occasionally transplant them to a reusable (and printable too) spool.
This is what I sometimes do, transfer a bit of filament to a mini roll. There are a few decent files out there for re-spooling out there.
As environmental shakey 3d printing is, I am happy to be inconvenienced by cardboard spools, as that is one disposable things we can make not-plastic.
One interesting use for the ams system is automatic filament switching for when you want to finish a spool that has ??? Kg of filament left and you need a print to finish over night. Throw the questionable one in slot one and the new one in slot two, tell they system they are they same and it will switch over on run out.
