I mean, I of course would welcome such an idea - but there's that strong contingent here who go by the title on the front alone ... and everything else must be thoroughly excluded (even when it's vague like the Godzilla set, or these shorts collections: what's a short and what's a bonus feature?).
Its just a weird curio and a nifty bonus for those who own it. Since you have to do some digging to find these shorts, its kinda more of an easter egg bonus than an included short. But still (as has always been my argument) - you can't separate these films from the set; and by buying the product, you also get these additional films as well as the "main feature" - no matter what the front cover says.
Here's the scale of the issue: https://www.icheckmovies.com/lists/crit ... van+dutch/
Especially as it would create 227+ new checks!
But again, we've had this argument before, it goes nowhere, and I seem to be the only advocate for it. An' ye harm none, do what ye will.
