I disagree with the idea that women are encouraging approaches. Most women in most settings are actively trying to discourage approaches.
Women have spent the last 20 years using earbuds/headphones to discourage approaches in the gym, on outdoor paths, and at parks. That's probably also true of pure street game but I don't have much pure street game experience since my large US city isn't conducive to street game.
At parks and on paths, women will occasionally be together in groups of 2-3. A solo guy can approach these women but it's more challenging since there's a target woman and some secondary woman. Approaching an already isolated woman is going to be easier.
In the 2nd half of the 2010s prior to the pandemic, I was starting to see more women using earbuds in the grocery store. I think they were doing it to discourage approaches. I haven't noticed that in the 2020s. I don't think women are actively encouraging grocery store approaches either, but far fewer are wearing earbuds/headphones as compared to parks, paths, and the gym.
I have scaled back my bar approaches over time. Everything that I've heard has told me that even bar approaching has become less common.
The approach is becoming less common in general as more initiation has shifted to swipe apps and social media DMs.
