snapshot 21w08b feedback

concerning the latest minecraft snapshot, there are a few issues I would like to mention including: 

Gold Ore: gold has always been a fairly rare ore in Minecraft like diamond and emerald, but in this new snapshot it appears to be the same level of rarity as coal, in fact, more common than iron. I am able to find gold in shallow rivers and exposed in cave enterances. Gold being more common is very weird to see and I feel like it somewhat ruins the fun of mining for ores such as gold.

Bundles: bundles are a very handy tool for inventories, however, fetching a specific item from bundles is quite annoying since you have to pull out all the items you've put there before it. I hope in the official update we will be able to choose what item to grab from bundles.

Holes and ravines: the overworld has become a death trap to me and my friends, I've died countless times to random small holes in the ground that turn out to be huge ravines. It would certainly be great if there was a way to spot them or tell if it's as deep as it is, like how ravines are distinguishable.

Aside from that, the cave generation and new biomes are great and very enjoyable.
