PEP 832: virtual environment discovery

I think things have calmed down enough that I think people understand the options being presented. That means it’s time to see what people think I should do with the PEP. Below is a ranked choice poll I’m running for a week (until next Friday). The options run from “you’re wasting your time, Brett”, to “all the things!”, and various combinations in between. You will notice that if the PEP happens then I’m keeping .venv as a reasonable location suggestion for a virtual environment no matter what...

https://pyrefly.org/blog/too-many-type-checkers/ makes the reasonable case that you should type check your tests with as many type checkers as possible while sticking to one for your actual code. That way you minimize those "<type checker> didn't like your API" issues.
Are you really expected to run five type-checkers now? | Pyrefly

Library maintainers may feel overwhelmed by the plurality of type checkers that exist. We offer some guidance on how to focus their efforts where they matter most.
