Why are confirmations desired?
Security that someone won’t rewrite the chain and undo the transaction.
Everything else equal, faster blocks have less security so you need more confirmations to get the same level of security that you would get from slower blocks.
With the same hash rate, you would need 5 two minute blocks to obtain the same level of security as 1 ten minute block.
