After all, they might not tell that much about the state of WasmGC as a lot of this is still heavily influenced by user space code as mentioned above. The numbers are going to be more meaningful once we have reached a more stable state and are ready to roll it out to external users.

Jetbrains themselves surely have feedback on WasmGC in general but likely limited insights from the trial itself. They might have received feedback from their partners though that I can ask them about.
