It's pretty bloated and slow compared to alternatives. This may improve if WasmGC gets integrated instead of part of the payload, but it's still not a great solution, especially on constrained devices. The flip side, is running in server mode means the laggy round trip actions that feel somewhat painful in contrast, reminding me of ASP.Net WebForms and how painful that was in practice.
