CLI has no --quiet/--silent flag to suppress non-essential output

Which client?

CLI

The problem

Every CLI invocation prints banner/status lines in addition to the actual result. That gets in the way when the CLI is called from a script and only the result payload matters (e.g. piped to jq) -- right now the only way to isolate it is fragile text-processing of the full output.

Solution you have in mind (optional)

Add a --quiet/-q flag that suppresses everything except the result payload (or the error, on failure), consistent with common CLI conventions.
