Yes, I have the X-T2 and use tethering plugin with Lightroom. It's the same software as the X-T1 and GFX50S.
Works as well as any other tethering plugin - just purchase from Adobe and the Creative Cloud app will download and install it automatically.
Sucks to have to pay for it in my opinion.
I haven't used the new X-Acquire software as I wanted to tether directly to Lightroom.
