#3763 introduced a new type export in icu-messageformat-parser/types.ts:

export type IntlLocaleLike = {
  readonly hourCycle?: Intl.LocaleHourCycleKey
  readonly hourCycles?: Array<Intl.LocaleHourCycleKey>
}

It isn't referred to by any other code in that PR, nor anywhere else in the repo, and doesn't seem to be used in any other GitHub repo based on a quick search. Does it serve a purpose?

I only ask because there is a proposal to refactor Intl.Locale in the TypeScript library which would break this type declaration, so wondered if it would be easier to pre-emptively remove it entirely.
