Incorporating some of the suggestions that have come up on this thread, the proposed IDL might be something like:

enum RemoveState {
  "no", // Not yet removed

partial interface Animation {
  attribute EventHandler onremove;
  readonly attribute RemoveState removed;

  void commitComputedStyles(optional sequence<DOMString> propertiesToCommit);
  void persist();

 Constructor (DOMString type, optional AnimationRemoveEvent eventInitDict)]
interface AnimationRemoveEvent : Event {
    readonly attribute double? timelineTime;
    readonly attribute CSSStyleDeclaration computedStyle;
    readonly attribute StylePropertyMapReadOnly computedStyleMap;

dictionary AnimationRemoveEventInit : EventInit {
  double? timelineTime = null;
  CSSStyleDeclaration computedStyle;
  StylePropertyMapReadOnly computedStyleMap;

Or, alternatively:

enum CommitKeyword = { "all", "none" };

partial dictionary KeyframeEffectOptions {
  commit: CommitKeyword or sequence<string> = "none";

partial interface KeyframeEffect {
  readonly attribute (CommitKeyword or FrozenArray<string>) commit;

Unfortunately, I don't think the latter alone covers the case where the author wants to persist the full effect so I suspect we would need most of the first part too (but probably minus the `commitComputedStyles` part).
