Any issue or PR on GitHub to track version catalogs support?

AFAIK no. Team is focused right now on new definitions approach shown by Paul on Kotlinconf, then, as I know, they will try to solve version catalog support problem. as a workaround you could use DG types in

gradle.kts

with

org.gradle.kotlin.dsl.dcl=true

enabled. Then it is possible to pass dependencies defined in version catalog
