Most of it is still data spam and data spam consolidations.
It doesn't surprise me at all. If fees will be too low, then users will use them to push transactions, which they otherwise wouldn't push on-chain.
For example: if free transactions would be allowed, and displayed by many block explorers, then we would see constantly filled mempools with around 300 MB of data, or other maximum value, accepted by a given node.
Also, there is one important aspect in all of that: "relayed" doesn't mean "confirmed". Even if some transaction at 0.1 sat/vB is "relayed", then it can be constantly broadcasted and dropped every two weeks, before actually landing in a block. A good example is how long you had to wait
to sweep 40 satoshis:
Deposit confirmed: 2025-09-12 08:21:47
Coins moved again: 2025-10-12 08:51:31
See? A month between getting some dust, and spending it at 0.21 sat/vB.
And, like it was with 1 sat/vB: using just 1.01 sat/vB, or even 1.02 sat/vB, was quite profitable, when a lot of people were stuck at exactly 1.00 sat/vB. The same can be true here: if we will finally reach 0.1 sat/vB in practice, then still: using 0.101 sat/vB, or 0.102 sat/vB may be a better idea, if there will be a wall of 100 MB or 200 MB of transactions with minimal fees.
