Obtainable Blocks - The Shrieker Effect

So this was sparked from my last created suggestion/ feedback but having some blocks accessible with the Shrieker effect in play..
What is the Shrieker effect?. Well the Shrieker effect is when a block should not be obtainable in its world gen state but is made obtainable without the blocks full functioning feature/s such as how the Shrieker summons the Warden when is made through world gen but when the player gains access to this block themselves the Warden now no longers is able to be summoned with it..
Items such as Spawners, Trial Spawners, The Vault, Reinforced Deepslate etc. etc.
These blocks seem really cool for decorative blocks and having it so that if a player were to obtain it making its full effect unaccessible to player but giving the player the ability to go crazy in survival with decorative blocks will provide some life for older content..
Players only have a finite source of Reinforced Deepslate and unless Mojang decides to add a recipe for it players will have a continuous reason to look for Ancient Cities, Dungeons, Trial Dungeons etc.

I dont expect this to be added but if it doesnt get added then y'all really need to look into making blocks that look very similar to all the blocks that players want to use but cannot in survival..
