Questions about the account model compared to the UTXO model

In a UTXO blockchain it’s possible to pay many people using one “transaction.”

For example this counts as a single transaction but has 2,500 outputs.

It’s also possible to consolidate many addresses into a single one with one transaction.

Exchanges use this technique with Bitcoin to save large amounts of blockspace.

It seems like an extremely easy way to optimize blockspace usage by pooling transaction with many people using a contract, especially because account transactions are smaller than UTXO ones.

I’ve looked at ETH block explores and haven’t seen this happen, is it not possible to do in the account model? if it isn’t why?
