A question about tournaments.

Apologies if this has been discussed before, but as I sit in this limbo in between Plat and champs and dream of a future of keys. Assuming no more brackets are added in above legends. Does the barrier to entry continue to scale. For example, if it can be applied here, let's say to rank high enough to even get a key in a tourney you need a minimum LTC of 50q and lifetime stones 150k. In a year's time will those mins stay stagnant or get even higher? Do the proverbial goal posts keep moving with the top players or do the brackets just keep getting wider?
