You can do that and indeed could do that before Google+ was even announced. It wasn't even tricky, you could create lists, set any one as the default, then when you wen to post just click and select the lists you wanted to appear to, or alternatively the ones you didn't want it to appear to.

I never got the whole circles thing as a unique selling point... like that functionality existed in Facebook beforehand and the reason people didn't use it much is simply because for a personal social media it's not that useful. I've used it maybe a handful of times in 10 years.

I mean I guess maybe because circles are a nicer design concept?
