There are blocks that are exclusive to some versions, such as the camera block - there's no PC version equivalent of that, and if a PE player placed such a block, it would most likely crash all PC players coming near that block. We could do some filtering, simple substitutions before sending the blocks to clients (replace camera block with a planks block), there's even a fairly performant way to do that (a lookup table), but it's so much work with very little real benefit, that it's unlikely to ever get done, unless someone actually decides it's his lifetime hobby.
