Warden leaves echo crystals where it steps, so you want to stay nearby it

Given the changes from the recent Minecraft preview where hitting the creaking spawns resin, I think that style of “getting greedy” is actually an excellent idea for mobs otherwise meant to be avoided. An excellent alternative would be if the warden left echo crystals behind on deepslate as it walks (similar in look to grown amethyst from geodes), but when it burrows the crystals disappear. Mining them of course gives off a sound and raises its aggro. The echo shards could also be given new applications like resin has, as opposed to just being useful for the echo compass. Blocks similar to amethyst with similar applications in making sounds when you walk on them, a trim color that’s closer to a dark teal, and an application with sculk sensors like what amethyst. Doesn’t need to be a direct comparison to amethyst though, just thinking they already share some similarities so it could be interesting. I mostly just enjoy the idea of “I want to run away from the warden but… I also want some shards…”
