Will there be any changes to mod pools and mod requirements in poe2?

We have heard the devs talk multiple times about making it so that it is possible foritems that are "just picked of the ground" to be very good again and to encourage players to identify more items. But how will this be achieved and how will ggg encourage players to actually pick up rares and identify them?

In poe 1, the mod pools are too diluted, wich makes it extremely rare that any given dropped rare will roll into an usable item. but even then, there are so few "filler mods" that removing them will do near nothing. I imagine GGG will either further specialise item bases (eg:life regen can only ever roll on armour bases), or to somehow dynamically "remove" undisired mods from the pool (like fire enemies cant drop loot with ice mods and low-level fire mods, or adding a "maximum item level to each mod").
