That is my understanding of what they did.
"Scala 3 takes a slightly different approach [from Scala 2] and focuses on intent rather than mechanism. Instead of offering one very powerful feature, Scala 3 offers multiple tailored language features, allowing programmers to directly express their intent"
So rather than something like implicits, that can be used N different ways, only 2 of which are practical, Scala 3 adds those 2 features explicitly.
