A New Minecraft item?

I was Thinking the other day about how annoying it is to get per say diamond armour and have it break mid armour today getting netherite or diamond is no easy task it takes hrs of bed bombing or strip mining just for this i was suggesting that in the trial chambers(or a new structure) it is possible to get an enchanting book with a 1.5% chance of dropping from a trial chamber its name is Unbreakable makes ur armour unbreakable its super hard to get so because of this is super OP lemme know what u think
