Rather, start from a software craftsmanship mindset even for the earliest stages of prototypes, and certainly for things that actually yield production-facing models or tools.
One big piece of advice along these lines is to use containers, VMs, and environment management tools, as well as build tools, all the time. This stuff should absolutely be part of the first commits to your new prototype's repo.
Choose something that works well for the team overall, codify it in writing with some team agreements on the expected standards, and then really stick to it. Banish the temptation to just tweak some code and run an experiment in an ad hoc way. You'll quickly realize that this constraint causes you to solve problems faster and enables more experimentation, even if you can feel like your ad hoc freedom is encroached on at the start.
Just one example might be using a Docker container along with your programming language's packaging tooling in order to standardize the exact training-time software environment, and to either use an external config file or use environment variables defined in e.g. a Dockerfile as the source-controlled means by which dimensions of variability are allowed to change.
Want to re-train the model exactly? It should be as simple as checking out the repo and e.g. running one Make command that rebuilds a Docker container for you, retrieves the right data for you, sets environment variables, etc.
Want to vary that model to do an experiment with a new version of TensorFlow, a new CUDNN version, a new model architecture, swap in a new classifier algorithm, etc.? Then you should be making a branch in version control for your experiment and changing these items in source code (whether the Makefile source, Dockerfile source, or actual code), so that the experiment can be reproduced by CI, by teammates, etc., and they can easily see the code defining the experiment during code review e.g. with a pull request or a similar tool.
You would be totally free to use this article's recommended PEDL if you want, but use it inside the defined environment. Not externally, as merely some ad hoc thing installed on your machine or your local work environment.
I could go on about how this will give other benefits, like discouraging people from writing experiments into an inappropriate environment, like a Jupyter notebook, but maybe that is for another time.
