First of all, I've confirmed that the hotplug protocol for both DP 1.2 and 1.4 is identical, as well as the EDID (thanks, backward compatibility!)

One thing I'm currently unsure about is

1) How not to degrade DP 1.4 signal so 144Hz signal is not corrupted upstream

2) How to continuously provide EDID signal so the graphic card doesn't go crazy when the monitor is turned off (nobody knows how well the hardware handles having nothing inputted when it should)

So here's a plan on the research aspect: (feel free to provide information through the chat feature)
