Previously the Expr returned by getOperand() was actually the subexpression common to the "ready", "suspend", and "resume" expressions, which often isn't just the operand but e.g. await_transform() called on the operand. It's important for the AST to expose the operand as written in the source for traversals and tools like clangd to work correctly.
