Manual AbortController vs internal debounce logic for VeeValidate async validation

VeeValidate supports asynchronous validation by returning a Promise, allowing for server‑side checks like username availability. However, the library does not natively cancel pending requests when the input value changes again. This creates a risk of race conditions where a slower, older request might resolve after a newer one, overwriting the state with stale validation data.

To maintain UI consistency, developers generally choose between two patterns: manually managing an AbortController within the validator function to cancel previous fetch calls, or implementing a debounce wrapper to prevent the validator from firing until the user has stopped typing.

Since VeeValidate does not provide a built‑in hook to intercept the lifecycle of a pending async validation task, the choice impacts how network resources and UI state transitions are handled.

• Which approach provides more robust protection against race conditions in high‑latency environments?
• Does a debounced validator sufficiently resolve the stale state issue, or is manual request cancellation strictly necessary?
