Did Apple undo whatever they did to slow down iPhones?

I have iPhone 6S. Up until now, I was on iOS 10.xx. My phone has been working fine. And I hadn't upgraded to iOS 11 yet just because everything was working fine. The phone's speed is almost as good as it was when I first purchased it in 2015. I was never affected by "Apple deliberately slowing down iPhones" issue maybe because I never upgraded to 11. Today, I decided to finally upgrade to the latest iOS available. And currently, the phone is being upgraded to whatever the latest iOS was available. Just wondering if there are any issues with iOS 11 or if it's completely issue-free now?

Edit:
Upgraded to 11.3.1

You have some control over that power management function as of iOS 11.3 (where it is disabled by default):

After updating my iPhone 6 to iOS 11, it was significantly slower. It wasn’t a battery issue, just normal slowness. The camera app is the worst, takes a good 5 seconds before I can take a picture.

Makes one want to upgrade to a newer device just so the phone is useable...

iPhone 6 definitely runs slower on iOS 11. You can do a restore to see if the phone gains some speed.
