Archaeology: a detailed feedback to improve it!

Activities are important in Minecraft, such as building, mining, combat, farming... and archaeology adds more activities in Minecraft, which is always nice to have! It seems like an idea from mods, but being a bit mod-like is a VERY good thing, as it prevents vanilla Minecraft from becoming too stale and boring.

There are, however, problems in archaeology. Judging from Minecon Live, it seems to be a non-repeatable activity. Something that players do only once or twice, as those archaeology structures probably won't be everywhere like ores in mining. You should be able to do archaeology in a LOT more areas, from temples to ocean ruins to nether bastions, even end cities.

Having unique archaeology items shatter in front of your eyes could also be very painful. By giving players more opportunities to do archaeology, at least they could try again. Ideally though, the process should be renewable somehow, so players can continue to do archaeology as an activity, and without the sting of items being forever gone. Archaeology could also have progression, such as grinding for a better brush.

Another problem I see is that archaeology seems to be mostly for cosmetics. That's well and good, but something unique and exciting needs to be in archaeology to draw players in. Perhaps a compass that leads to an ancient underground city, filled with loot and dangerous mobs? Or items from a lost civilization, to construct ancient golems and weapons? They're a lot more appealing to players!
