We left off near that conclusion (https://reviews.llvm.org/D68115#1686887); however, `-ftrivial-auto-var-init=` merely increases the chance that code expecting the zeroing to occur would break. A separate option to control zeroing for union padding would help in cases where the zeroing does not happen for reasons other than `-ftrivial-auto-var-init`.
