Whats the current state of testnet3 vs testnet4?

Easier to mine a block with real difficulty than with difficulty 1.

At least wipe out all CPU-blocks mined before your block if you do that.

Seems like SoloPool.com started applying this: https://mempool.space/testnet4/block/0000000000000001b36fc5289b8441e8d298d0a4bcb6892665c2a13a0a4b5bfa.

I can't really tell if they wiped out blocks from this data.
It looks like they're just mining CPU blocks by themselves, then their ASIC block secured their own CPU blocks. Look at block 160104 for example: there's a row of SoloPool blocks, but they're all CPU blocks.
