How can you be so sure about that? I still see ridiculously large squares in the blocks at mempool.space. I think if it was over yet, there would be no transactions costing more than 10k sats in each block.

There are always large transactions. Consolidations and payouts, for example. Here's one from last block (777665) that consolidated 500 inputs for 531,102 sat fee.
