I see that the patch introduced a bunch of `echo` lines, which could be good for debugging but can be a pain when using kamctl many times, specially when one wants to divert the output to a file or pipe for further processing (e.g., output of a kamctl rpc command which should be just the jsonrpc output that then can be processed with `jq`).
Either remove them or replace with `mdbg` (an internal function for debug messages).
