Also it is important to note that we don't know how DUP voters feel about Brexit, the GFA or the relative hardness and positions of borders. All we know is they voted DUP in elections where people tend very strongly towards voting along ideological/religious lines.
So something would be negotiated between the left-leaning parties (all of which supported Remain in the referendum and prefer a soft or Brexit-in-name-only Brexit,) possibly even getting a second, better informed referendum. It couldn't be any worse than the divisions within the Conservatives, it would better represent how the people of the UK voted and the NI issue could be discussed without DUP hardliners threatening to topple the government.
