Idea for sift rifts-infectedstructures with contained spread

Hello Mojang, For The Sift update in 2027, please don't make rifts spawn randomly around the world. It would feel like a huge disturbance to the Overworld and would not feel like Minecraft. My suggestion is to have a script/timetable for where rifts appear and which biomes they are likely to appear in. You could add small areas where Deep Dark sculk is spreading to the top of the Overworld. These could appear as infected ruin portals, and also appear in abandoned camp sites, abandoned villages, and ravines leaking sculk out. This could also affect Nether ruin portals and End portals. When you activate an infected Nether portal, a small Sift rift could appear below or above you, and an infected End portal could work the same way. This would make it a mystery and explain the rift patch. To avoid the infection covering the entire Overworld or destroying world generation, there should be a border around each source (ancient city or ruin portal or abandoned structure). At that border there should be sculk with souls coming out of it. The border should be about 10-20 blocks from the source, and 5-8 blocks high if the infection is leaking out on a wall This should be most likely to occur near the surface but not only underground, so players can easily find it. It should also most likely not spawn near the player's spawn point unless changed in settings. This system fixes the problem of random rifts ruining the world and makes the idea suitable to add to the game. Thank you.
