At the moment, the construction wand only copies the "raw" blocks and discards all blockentity data (which makes sense for most blocks). I would like to request an API (preferably one that allows for optional compat without self-mixins) that allows consumption of additional materials and post-processing of the placed block in order to copy over additional data from the source block's blockentity. This would allow me to implement support for ConstructionWand in FramedBlocks to copy over the camo and other attributes stored on the BE.
