It is possible to setup a lot of nodes having clocks set back more than 3 minutes. Those nodes will reject any blocks from other nodes with valid clocks settings. Having majority of malformed nodes on the network would let attackers to compromise blockchain.
Growing network will make it harder to perform the attack. But potentially it still exists.
Need to implement median network time measurement to show user a warning.
