Problem

Create a new project that has simple tsconfig and open a single .ts file with the contents:

import fs from 'fs';

After opening this project in VS Code, I notice a large number of fs.stat calls into /Users/matb/Library/Caches/typescript/5.0/, where automatically acquired types are stored. However according to the TS Server log, none of these files end up in the project

Here's a log of all the file stat calls when opening this one file: tsSyncCalls.txt

The location checks in /Users/matb/Library/Caches/typescript/5.0/ are coming from typing installer as it initialises and processes global cache. I think this can be deferred till we really get the request though. Will experiment.
