What about reserve_transfer_assets usage?

[gitofdeepanshu]

removed the usage of reserve_transfer_assets from parachain calls in tests.

[Dinonard]

No more substantial comments, but we need to discuss first whether to block old calls immediately or later.

[Dinonard]

Forgot about this one in runtime .toml files:

# TODO: remove this once we get rid of `pallet-xcm` fork & double dep
polkadot-runtime = { workspace = true, optional = true }

Please remove this now.
