Lake Formation Column-based access on a resource link

First, what I see in the very last screenshot image of the Granting resource link permissions page is that the 'column based permissions' option is disabled ...

..., but in our account, for a resource link I have a different presentation with different options, no super.

1. Not blocker : I wonder if the difference between the two images is only a recent change in the interface.
2. Blocker: Why it isn't possible to grant column-bassed permissions on a resource link?

Our use case is the following.

• Producer account : Sharing 'tableA' with an external account (Consumer) with Alter, Describe, Insert & Select permissions with all columns. Done with both cross account versions
• Consumer account:
  • Create resource link tableA_producer from the Producer.tableA shared table.
  • Trying to grant access to some users to tableA_producer, but to only some columns ... But what I see now is that it is not possible, why ? We don't want to do multiple resource sharings from Prod for the same resource.

Bonus question : What are the differences between the 'cross account version settings' version 1 and 2 ?
