Me and many other people think that the new Blueprints should not be one time use as it does not make any sense as why would a blueprint disappear? Its just a nuisance for the player.
They are one time use because you need to sacrifice 3 minges and spread their blood over it to make a zarp logo, than pray to the great Lead Team to fufill your wishes and teach you how to craft the new unholy items...
Think it this way, you get all blueprints then there is no more fun and will get boring making it all one time use apart from molotov and Printer Booster makes it all much better and something to work for.
The point isn't to make it easy, it should be a process you put effort into.
Note: Otherwise the current price of all these new items will be way... lower, which i'm sure some people wouldn't want to happen.
