Any reason for dropping null from the types for ParsedQueryString

[birtles]

Prior to c2ab7cd ("Require Node.js 14 and move to ESM"), ParsedQueryString was defined as:

export interface ParsedQuery<T = string> {
	[key: string]: T | null | Array<T | null>;
}

But that patch made it

export type ParsedQuery<T = string> = Record<string, T | undefined | Array<T | undefined>>;

Was that change intentional? I can't see anything about it in the release notes and the docs still say that:

Note that keys with undefined as the value are always skipped.

And if that's true, are we expecting to be passed back keys with undefined values from parsing while passing in null values for keys with don't have a value?
