Wow. This can explain some of excesive swap usage on M1.

Seems like a poor conclusion to draw with this little information.
People have reported their SSDs filling up (in terms of total writes) much faster on Apple Silicon machines. If IOAccelerator can leak like this then it would definitely explain it. 25GB swap for one image is absurd. Multiply that by a few months of usage. It may not be a smoking gun but it is a fingerprint in the pool of blood.
If this were the cause people would have noticed having 0% free memory way before their SSDs started dying.
That’s been debunked.
It hasn't been debunked if there's no source for the claim...
Apple said that the kernel interface used by smartctl is emitting invalid data, which invalidates all conclusions drawn from it, such as “there is/isn’t a problem with SSD wear”.
Can you provide a link please?

I compared smartctl output with activity monitor on disk writes and it's exactly the same number. You can do the same.

Perhaps, but if you read the Twitter thread others are suggesting the same thing and people seem excited/happy that there is possibly a potential fix that may come from Gus discovering this.

So, maybe premature to get too hopeful but certainly not too soon to look in that direction?

People are suggesting the same thing because it sounds nice to be able to correlate them, but the evidence just does not exist yet. At the moment is seems somewhat likely that they are correlated at all, really.
And yet it's relatively performant, says a bit about the quality of components in apple hardware (SSD in this case)!
