This has been common in Sweden for decades, I had it in my previous house almost 20 years ago. If I remember correctly it was a 100m borehole. The only limitation is that certain soil/rock environments work better than others, so it’s not suitable for all locations.
Heated our house in northen Sweden just fine in -20/30C winters.
Which isn’t as large as the MS cuts coming today of course, but per the rumoured details (all managers and creative directors being safe) it seemed laying them off was easy enough.
That being said the rumours I’ve heard for the Swedish companies under MS have been largely spared, and there unionisation is of course relatively common.
