Structure Tags

What is it? The title is fairly self-explanatory, however, all I am asking is for a tag type for structures as we currently do NOT have the option of structure tags. 

Why? Minecraft already has some tags used to group certain structures together to help group them together by type.
 

How would this work?

1. Common Structures Tags
   1. mineshaft
   2. ocean_ruins
   3. ruined_portal
   4. shipwreck
   5. village
2. Minecraft also has tags for structures that appear on explorer maps and structures with specific entity spawns and dolphin located structures
3. Custom Tags
   1. This would allow us to ensure that structures of the same type share spacing.
      1. fort1 and fort2, as of currently, could generate side by side or within close quarters even if they are variations of the same structure. This would use structure tags to group these structures together to share spacing
   2. Custom Blockly Blocks to use these tags could include
      1. Creature spawn conditions such as "is structure tagged: []"
   3. Additionally, a new tab for this on structures element would be nice for things such as
      1. Can dolphins locate structure - tag [minecraft:dolphin_located]
      2. Can structure be located by eye of ender [minecraft:eye_of_ender_located]
      3. Ocean Map  - If checked gives structure [minecraft:on_ocean_explorer_maps]
      4. Treasure Map - tags [minecraft:on_treasure_maps]
      5. Trial Map - tags [minecraft:on_trial_chambers_maps]
      6. Woodland Map - tags [minecraft:on_woodland_explorer_maps]
