you can put an item into a black hole unit, break it and it will retain said item
when you put that (full) black hole unit in another black hole unit you can add more (empty) black hole units to get the (full) black hole units

FIX: blacklist inventory blocks like black hole units in a black hole unit
Better fix: have black hole units check for complete item data

It would be great if there was a config to add items to the black hole unit / controller blacklist
or at least a crafttweaker api that could add a custom blacklist

Or you could add a custom "oreInventory" specifier which would be always blacklisted to which we could add items via crafttweaker scripts ;)

So has it been fixed?

yes

Thank you.

Awesome :D
