It's not a problem anymore since most Apple devices are ridiculously overpowered and they have separated iOS from iPadOS.
It's hard to fault them honestly, most people don't understand how degraded batteries affect their device, they think it's just about how many hours the device lasts on a full charge, when in reality it's much more complex.

I’m also not sure why “just once” is supposed to buy back trust. They still don’t allow for iOS downgrades, so the underlying issue hasn’t been addressed.
Took them like two weeks to release a patch where you can pick which option you like.
As someone who had an iPhone that claimed to have 30-40% battery and then just shut down completely when trying to make a call, I really would've preferred the slowdown option.
It was fixed by a 50€ new battery.
There was literally no malice here, a very serious bug that obsoleted an otherwise out-of-support device of their got fixed. Sure, the best option is the one that was later implemented (people can choose which option they prefer) thanks to governments(!), but let’s not sell this story as something else.
The Mini 2 was ruined by iOS 11. I was lucky that I was able to immediately downgrade back to iOS 10.
iPhone 3G was made unusable by iOS 4.
