Inconsistency between jsconfig.json and next.config.js

[anmonteiro]

I have a project where I run Next.js in a subdirectory. My dev script is e.g. next dev ./subdir.

I was trying to set up the new absolute import scheme detailed in the 9.4 release, and found out that, while next.config.js needs to sit at the root of the repository, jsconfig.json only works if specificed in the subdirectory.

So this works:

├── subdir
│   ├── jsconfig.json
│   ├── pages
│   │   └── index.js
└── next.config.js

But this doesn't:

├── subdir
│   ├── pages
│   │   └── index.js
├── jsconfig.json
└── next.config.js

That took me a while to figure out. Is this by design? Note that I'm very much out of my depth, I don't really know how jsconfig.json is used outside of the scope of Next.js.
