There was a problem hiding this comment.
This is intentionally retained compatibility debt. Historical bundles call handlers with only ...backendFunctionArgs and may read raw context from globalThis.$; changing either behavior would break existing customer functions. The SDK/runtime bridge is the migration path, and removal requires a breaking release.

What and why?
Preserve the exact backend-function behavior existing customer code was built against while introducing the stable SDK migration path. Customer handlers historically receive only backendFunctionArgs and may read the raw runtime context through globalThis.$, so changing either behavior would be breaking.
