Formulating a proposed solution to microsoft/TypeScript#44597 ...

I see that modifications to this can be a breaking change.

However, as it is currently implemented, it is not intuitive.

Besides a format that would be preferred (because it's shorter) and breaking, I see at least one way to add this functionality in a non-breaking way.

Example:

// extending from:
types: {
   "svelte": true,
   "wewanttogetridofthis": 1
}

// root
types: {
   "node": true,
   "jest": 1, // example to write it shorter
   "wewanttogetridofthis": false // remove the dependency by making it falsy
}

It could be implemented in a way that the to-be-extended-from config can use arrays (equal to { dep1: true, dep2: true }) and the root, the referencing config uses the object notation.

Just as an inspiration.

Another, of course breaking, format change would be to introduce a "!" prefix to module names, allowing the referencing config to cancel a module name by adding !wewanttogetridofthis to the array. (Just for completeness.)

If you insist on not touching the compiler config system, could you/we at least add a note to the documentation at:

• https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#tsconfig-bases
• and https://www.typescriptlang.org/tsconfig#extends
• and maybe https://www.typescriptlang.org/tsconfig#types

?
