Respawn anchors cannot be mined with any pickaxe, unlike ender chests, enchantment tables, and other related blocks

Despite being a utility block, respawn anchors cannot be mined with any pickaxe, unlike other utility blocks. This is inconsistent with the following utility blocks, which can be mined with any pickaxe, despite being made of higher materials: ender chest, enchantment table, anvil, cauldron, bell, blast furnace, smithing table, and mob spawner.
