Make Swift Sneak Renewable

As of right now, the Swift Sneak enchantment has one major flaw, that it is too rare, especially on servers. Getting enough Swift Sneak to supply many server members can be virtually impossible. I believe the reason that this feature wasn't implemented yet is the fact that the Mojang Devs want swift sneak to obtained in the Ancient City, and adding yet another way to bypass this makes raiding them even more unavailing than they already are. I came up with two ideas which are both based on the Ancient Cities.

• Enchantment Table Modification: Have an Ancient City only item, like echo shards, be able to modify enchantment tables in some way. Maybe they could be used to craft a totem block that when placed near an enchantment table would give it the chance of getting Swift Sneak.  Alternatively, you could craft an entirely new enchantment table by surrounding the current one with echo shards in a crafting table. This would enable Swift Sneak to be renewable while also still requiring looting the Ancient Cities.
• Reinforced Enchantment Tables: An immovable and unbreakable enchantment table found in the Heart of Ancient Cities, forcing players to return to Ancient Cities if they want more Swift Sneak. One idea I had is that whenever they are used, they shriek, increasing the chance of summoning the warden, adding much more tension when using them.

Thanks for taking the time to read my suggestion, I believe that this feature could be very beneficial to large servers.
