Thanks for your patience, @o-l-a-v — this was recently picked up as an outstanding open issue for the ARM Deployments team to review.

Reproduced on current CLI (2.85.0): az bicep upgrade --only-show-errors still emits a non-error status line to stdout (in my run, Bicep CLI 0.43.8 is already installed …) even though nothing went wrong. The cause is that these status messages are written straight to stdout via print(), while --only-show-errors only adjusts the logging level — so a raw print() slips past it.

The fix is CLI-side: route the bicep command's status output through the logger (at info/warning level) so --only-show-errors and --output none can suppress it.

Leaving this open — thanks for the clear repro.
