I did already. There are multiple issues with that approach: you get only flavor of how to do things, unless you keep jumping teams over and over again for years. It's extremely inefficient way of learning this.
You're also putting the burden on the folks in charge to know what's out there and pass it down to you, instead of actually doing your own research.
Also, sometimes those people don't know what they're doing and they're struggling just as much as you would be in their position, so now you're learning from people who are making it up as they go, which you could have done equally as well by yourself.
