I don't understand what some of the utility types in query-core do.

[novice0840]

This is a utility type in file "types" in package "query-core"

I understand that the type has the ability to omit the TKey from TObject, so I'm taking that type and creating a third argument there called TStrictly to control the range that the Tkey value can have based on the value of the argument.

The problem is "Record<never, never>". I understand that this represents an empty object, but I don't understand how "string & Record<never, never>" is different from just "string".

In fact, when I experimented with both types in the Typescript playground, I got the same result: both types allow only strings to be entered.

If I'm misunderstanding something, please let me know.
