Yea it's hard to say without context, I just gave the generic answer. I'm not sure you ever 'need' a garbage collector, and if avoiding one lets me save 20k in cloud expenses a year on a small team, it's probably worth it, because after scale out 20k isn't 20k anymore.

That said, people misuse technology all the dang time(I've done it). And in general I agree, Go is usually enough and has the best cloud ecosystem. I've had trouble with large go code bases exploding over time and requiring a lot of bodies to maintain compared with rust/scala.

Sometimes it's hard to speculate when one tool is clearly better than another. Some companies just want to use new stuff to sound cooler...
