Anything which makes your prod and local environment differ is a bad thing in my opinion

Unless you're writing code that only you will deploy to machines that you control, "prod" and "local" will always be different. If you're only targeting a fixed version of a fixed OS on a fixed architecture, then most things are easy.

For me "local" is a Mac running ARM, for the person pip installing my tool "prod" might be Linux or Windows. I cannot punt (or I can, but it would greatly diminish the usefulness of the stuff I develop) and say "your prod must equal my local or it won't work", I have to deal with it and I want tools that make this hard problem as easy as possible.
