Yes, really nice bit of kit, especially at that price. I’ve had a lot of fun with mine. gadgetiod helped me get an IR remote working with mine.
So far I’ve only run Stretch on one of my Pi’s. Most of my setups run headless so I’m just leaving those as is. No advantage to doing them all over gain.
I have plans to buy at least one of these USB Console adapters https://www.adafruit.com/product/3589 For use on my headless setups like the pirate radio. Want to see if it will make it easier to do things like fixing the loud click issue etc without having to hook up a monitor keyboard etc. I have a couple of headless setups that don’t have WIFI or any Internet connection. Pi A+'s with minimal hardware attached. So, no easy way to remote in via Putty etc.
