Can you clarify what will happen to certain legacy items in Standard after 3.28 deploys?

In particular, what will happen to each of the following existing items in Standard - will they be deleted / replaced with something / become unusable (except for in vendor recipes, say) / continue working:

- Growing Wombgift
- Scarab of Bisection
- T17 maps
- Breach blessings
- Vaal Breach gem
- accumulated Kirac missions

Thanks!

Good point, I'm also curious about this

What happens to collectible oldschool maps with the new map system?

We've found out about a few of the items from the original message, but would still like to know what will happen to the following in Standard:

- T17 maps (and more widely, other old maps)
- Breach blessings
- accumulated Kirac missions

Thanks!
