Bug: How to use --use-container for sam sync (because local python is not same as runtime)

I was able to build using --use-container so i dont have to bother about the local python version.

But while syncing it creates problem

$ sam sync --debug --stack-name santhosh-testing

This feature is currently in beta. Visit the docs page to learn more about the AWS Beta terms https://aws.amazon.com/service-terms/.

The SAM CLI will use the AWS Lambda, Amazon API Gateway, and AWS StepFunctions APIs to upload your code without 
performing a CloudFormation deployment. This will cause drift in your CloudFormation stack. 
**The sync command should only be used against a development stack**.

Confirm that you are synchronizing a development stack and want to turn on beta features.

Enter Y to proceed with the command, or enter N to cancel:

Thanks for the suggestions! I believe as this looks like a widely asked feature, we will definitely discuss about this and see if we can include this in recent releases!

I’d like to second this, not because I’m using a different runtime version locally, but because I develop on a Mac and (obviously) deploy to Linux. I’m going to try running sam sync inside a container mounted to my $PWD, but a --use-container flag would be really useful.
