why does command pnpm config set registry modifies the user npmrc file?

[mzleman]

I found a comfusing behaviour of pnpm.
description：

1. my os is windows
2. my pnpm version is v9.12.1
3. my npm user config file path is ~/.npmrc
4. and apparently my pnpm global config file path is ~/AppData/Local/pnpm/config/rc

when i ran command pnpm config --global set proxy ..., it modified pnpm global config file.
but when i ran command pnpm config --global set registry ..., it modified npm user config file.

questions：
Was it designed that way？
My expectation is that when I use the pnpm config --global set command, it should always modify the pnpm global file.
Is "registry" the only field that is special?

I am not sure why it happens. I think I would expect both to modify the global pnpm file.

thanks for comment. I think these codes make it happen. The --location parameter value in npm is "user" by default.
