I totally disagree. The earlier Macbook keyboards were far nicer to type on, in my opinion.
Perhaps you can't find a better flatter keyboard, but from a pure typing perspective, I think it's not good at all.
(Obviously, I'd hate this in an office space as well.)
I also don't get the point that MBPs need to weight less or become thinner. My MBP 2015 13" and 15" are light and thin enough as it is. The sacrifice isn't worth it.
I haven't personally encountered any issues of the keys sticking though I know people who have. That's a real and serious problem, although it sounds like Apple may have figured it out in later models. But personally I love the feel of the clicky short-travel 2017 keyboard. About the only thing I don't like is the arrow keys, I miss the cutouts above the left/right arrow keys to help find them easier.
Specifically the variants with the beam spring switch mechanism. You won't believe how much these go for on ebay:

And if you really want to go down the rabbit hole, check out this insanely detailed description of how the old selectric typewriters work (the beam spring was designed to replicate the feel of the selectric's wiffletree mechanism): https://www.youtube.com/watch?v=BJITkKaO0qA&t=597s
