Definitelytyped: @types/node Use Typescript 3.7 asserts syntax for node's assert function

[MajorBreakfast]

About the asserts feature:
https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html#assertion-functions
https://github.com/microsoft/TypeScript/pull/32695

Basically I would like to change:
https://github.com/DefinitelyTyped/DefinitelyTyped/blob/9f57df89f30bacee1d46dfbf40a08132b4b059ef/types/node/assert.d.ts#L2

into this:

function internal(value: any, message?: string | Error): asserts value;

Since this TypeScript feature has been released only recently, how should this best be added to the types without breaking compilation on older TypeScript versions?

Technically it's possible by adding a ts3.7 folder and add the modified asserts.d.ts file there. Maybe it's needed to copy also files from 3.2 folder perferred is to just include them instead of copy.
There are a few 3.2 extensions for APIs supporting BigInt.

But be aware that this adds mainainance effort as once assert is split up it has to be maintained in both files. For assert this is maybe not that bad because the APIs is not changing frequently.

Maybe we can bump up the ts3.2 folder to 3.7?
@RyanCavanaugh in this issue you mentioned you have telemetry, is this telemetry openly accessible?
It would be incredibly valuable for developers to be able to use this data in order to make support decisions for their packages.

This was somewhat recently done for invariant.

Type guards for built-in node assert functions would be really useful to have. Are they are plans to implement this?

Thanks.

For @types/assert it seems to be already done, see #41179. They made a ts3.7 sub-folder.

I've made a strawman PR to get the ball rolling :)

Just an FYI, this has been shipped, but currently won't work because the typesVersions property is being sorted before publishing, meaning that the new ts3.7 types are never actually applied.

This is being tracked by #44117
