Haywire? No, not likely. But something might just “not work”. Your doubt/concern is valid. Unlikely, but valid. Less likely to be a problem with tag export/import than graphics, from my experience. The key is to change your development process to ensure you are always working in an environment that matches your client’s environment. This is almost impossible to do if you are installing your development gateways on your local machine. Use virtual machines or containers, tailored to match the versions and installed modules of your client. Separate VMs for each client system.
