This is a video with a removed key from December MBP 2016 (at the very beginning)
This is a video with a removed key from March MBP 2016 (the video is dated in March, no idea when the MBP was bought)
This is a removed key from iFixit MB 2017 teardown

They seem the same. The only difference - MAYBE - is the material of that disc part, but it's hard to say if it's a different material or just lighting (judging by the second video it's just the lighting).
So, they pretty much look the same. Now, I don't know. My 2016 does not do that high-pitched thing, even when really heated up. And there are 2017 MBPs that do that high-pitched thing.
There were also rumors that Apple is changing the keys for 2016 models when you bring them in for service. No idea if this is true.
Now, draw your own conclusions. Maybe they did a minor tweak (known to happen). Maybe they didn't. Maybe people who feel the difference with 2017 models feel it because it's there. Maybe they are imagining it. Or, maybe - since even between same generation models there are different feeling keyboards - they had bad luck with previous ones and now they think new ones feel better, while in fact their previous ones felt bad.
I have no idea. I just know they look the same.
