Kotlin 2.0 & K2, what does this mean for Detekt?

[TWiStErRob]

Hi there, the news is out, K2 is coming soon (this or next year):
https://blog.jetbrains.com/kotlin/2023/02/k2-kotlin-2-0/

What does this mean for Detekt?
Is there a need for rewrite (PSI changes)?
Will we just get "free" performance?
Will it break the compiler plugin?
Will there be an actual Detekt 2.0? 😊

The K2 compiler gets a new frontend called frontend intermediate representation. As detekt relies on the PSI, this will most likely impact further development after K2 has been stable.

We could try with K2 earlier following the documentation to provide early feedback https://kotlinlang.org/docs/whatsnew-eap.html?_gl=1*1pf7wr0*_ga*MjA0MzU5OTIxMy4xNjc3NDQ4MzE3*_ga_9J976DJZ68*MTY3NzQ0ODMxNy4xLjEuMTY3NzQ0ODM4NS41NS4wLjA.&_ga=2.180902631.1599569198.1677448318-2043599213.1677448317#new-kotlin-k2-compiler-updates

Sneak peak: yes :D We're working on it <3

And yes, I believe that K2 would mean a lot of rules will have to be re-written or adapted.
Ideally we could make a community effort out of it.
