Are you open to using a tool like direnv to manage env vars on a directory-wide basis? I used to also suffer from the same paranoia, but direnv has allowed me to take back control regarding directory-specific configuration.

You can configure it to set your git user name/email based on your working directory, for example. This is how I keep the separation you mentioned between personal and work on the same machine

Would something like that exist on Windows?

Also, it doesn't seem to solve the problem of multiple accounts; I more or less accepted I need to manually configure user.name and user.email for each clone, but the account is not part of the same config, it looks like it's stored in some other ephemeral place - maybe GCM Core, or some Credential Manager or who knows.

I only realize it was using the wrong account when I try to push and get some unauthorized error; by that point, my commit log is polluted with the wrong account so I need to do some gymnastics where I reset the authentication, manually copy over files or unstage to purge the metadata, etc.
