I love boto, but when I filed the issue and received the answer from a committer, I decided to move to boto3. I can understand the situation but, boto seems to be be strictly backward compatible. So let's move on to boto3 and have nice Resource API with all AWS services.
print [i.console_output()['Output'] for i in boto3.resource('ec2').instances.filter(Filters=[{'Name': 'tag:Name', 'Values': ['frontend17']}])][0]
...is pretty awsesome!
