Kinda needs to be default. I mean, I’m a privacy buff, and I don’t care if you know my raw specs if I’m telling you how a game runs in a public forum. Because without the specs, that information is worthless.

I'm against sharing privacy information by default. This has to be opt-in. Also a review without specs is not worthless. All the years I found the reviews without specs still helpful in Steam. Having specs gives a little bit information, especially important when you want to understand some performance or compatibility issues. But most reviews don't need that.
