Hi Chris, There is an extensive summary document from the Sheets colleagues (including a tl;dr section in the beginning): go/sheets-wasm-corp-50 We believe that error count and crash rate (mostly OOM) regressions are caused by user space code but investigations are ongoing and we expect improvements over the next weeks.
Jetbrains is also using the OT for Kotlin, but I'm not aware of detailed insights. They advertised it in a talk at WasmIO <https://seb.deleuze.fr/introducing-kotlin-wasm/> a few months back.
