Permanent discounts back

I think me and the minecraft bedrock community would really enjoy if you guys added permanente discounts back, find the trade that you wanted is already hard enough bit now we need to also worry about the price, because, even after zombifying and curing the villager, the discount would go away after a while. All i want is the permanent discounts back, just that, im not asking to every trade to be 1 emerald again, no, i just want permanente discounts back
