Code analysis

Missing

WorkQueue -
i.e. rate limiting / requeue / relist intervals

all three are super key
- rate limiting ... don't want to overrun
- retry via requeue is a common controller pattern
- relist is key - receiving watch events are not guaranteed by k8s ... granted, there has been discussion over the years on how controller implementations either just relay on eventual k8s consistency, or do their own background queries if they depend on deletes for cleanup
    -- there is talk in issues about relist on connection re-establishment

Informer interface
- no has synced
	// HasSynced returns true if the shared informer's store has been
	// informed by at least one full LIST of the authoritative state
	// of the informer's object collection.  This is unrelated to "resync".
	//
	// Note that this doesn't tell you if an individual handler is synced!!
	// For that, please call HasSynced on the handle returned by
	// AddEventHandler.
	HasSynced() bool

- no event handler overrides
- no lower level watch error handling override
- no transforms
i.e. prune unused metadata to save mem
- no access to the watch cache


- see no thread safety around cache
   vs. Indexers and k8s client-go version of the cache .... where indexers also provided optimization around cache look up

events handling
- the update does not seem to provide before/after
