Am I correct in understanding that the WASM compiler for Kotlin is not using the multiplatform (or K2 in future) compiler frontend? Is there a reason for this?

It does use K2 in a way consistent with other platforms.
You need to enable it manually for 1.9.2*, see https://kotlinlang.org/docs/whatsnew1920.html#how-to-enable-the-kotlin-k2-compiler
K2 will be the default in 2.0
