I have the Tatra which I think is quite similar to the Lhasa, but a different leather (the Lhasa should be softer from what I understand).
For me, personally, it's overkill at least in spring-autumn. I use the Tatra (waxed leather, not the goretex version) in cold and wet weather in winter and am very happy with it under those conditions. Otherwise I prefer sandals.
I'd say the boots make more sense in slightly more mountainous terrain and cold weather, and are a bit too heavy and too warm for mostly flat and easy walking like for example the Francés in the warmer seasons.
But they're high quality boots. The first I ever had that don't give me blisters.
So if you're someone who prefers more sturdy shoes and/or want to walk a more technically difficult Camino, or plan to walk in winter, why not.
Most important is that they fit and feel comfortable to you!
