Echo Shards and the Invisible NBT Tag

The new Echo Shard item could be a great opportunity to enhance vanilla gameplay by introducing the Invisible tag to vanilla without the risk of losing invisible blocks. Echo shards could somehow be used to apply the Invisible tag to item frames and armor stands, as well as potentially create other invisible blocks in vanilla such as light source blocks or new echo blocks. In order to avoid losing these invisible blocks and entities, and Echo Spyglass could be crafted with shards that can reveal invisible blocks and entities (perhaps including mobs in this case as well). A means of removing the tag would be needed, and shards would need to be more common (unless an alternative way is made to give things the Invisible tag). However, this would ultimately open up a lot of fun building options now that invisible blocks are less problematic, and it adds some utility for non-builder playstyles by revealing invisible players and mobs. Perhaps the Echo Spyglass could also have a permanent Night Vision effect while using it to broaden its utility further.
