Yes, at work we've got a variety of standalone FLIR cameras (Taus, Bosons, Duos, the One and Leptons) - pretty much the entire camera core range. I work in ecology and occasionally for outreach or when working with non tech people, they're interested in seeing what thermal footage looks like. And for field work it's handy to have environmental measurements in case we want to correct for atmospheric conditions (rarely tbh). The FLIR One comes in a USB C model, I've played with that on my Pixel. Works great although I think you have to use the sdk to get any kind of useful information out of the camera (eg if you want raw data). My group specialises in drone imaging and often it's useful to have ground footage so you can compare simultaneously, for example during biodiversity surveys. The problem with the plug in solution is the risk of it getting lost in the field, and it's not rugged enough. We recently did some surveys on a lake, so an IP rated phone with everything integrated would be ideal.
