If this is a general suggestion about a switch that may be useful in combination with OpenWrt devices -- sure, I do see the relevance of that... but while this device is very clever, it doesn't have anything do to with OpenWrt. It's just another (cool and interesting) managed switch that can be used with any network (provided you also run the Unifi Network Application to configure the Unifi switch).
(full disclosure: Not bashing on UI at all here -- I've got a full Unifi stack and my YouTube suggestions often bring up things about their new product launches, so I've known about this product since the day it was announced).
