Changing it doesn’t make it less unique per se. FWIW, most modern OS’s allow you to change the MAC address of your computer to anything you want.

From what I’m [reading](https://www.reddit.com/r/Aqara/comments/1c2l372/comment/kzso4q6/), the reason for the change is that the MAC prefix was changed from a range belonging to Xiaomi to a range belonging to Lumi/Aqara.
