Did this for years with my ThunderBolt display, and have been doing it since 2015 with my LG 4K display.
The only bad thing is that because the LG is USB-C and not TB3, I only get USB 2.0 speeds out of it. I have a pair of USB-C to USB-A adapters that let me connect ethernet and my phone or other device to charge.
