Yesterday I came across the same issue (in beta1) where, because of a 
category -> subcategories -> products structure more than 40000 objects 
were validated when selecting the top category, as the @lazy was not 
taken into account.

For now I've done a quick hack by extending the CollectionValidator and 
check whether or not the validated object is an instance of 
\TYPO3\CMS\Extbase\Persistence\Generic\LazyObjectStorage

There might be a nicer/better way but I could not find one.
