Zip package unzipping zip file in contents

I have a package that contains a zip file that I would like to be deployed as a zip file but the GetPackage step has started unzipping the file. I am not sure which version this started in but I am sure that this wasn’t always the behaviour.

Is there an option to leave the zipped contents zipped?

This happened in 3.7.12 and I should use Transfer Package now instead.
