A. Use the 'APPLICATION$VERSION' function within a stored procedure to conditionally enable the feature and log the usage to a separate table. Make sure the logs are maintained within the producer account.

B. Create a separate role that is only granted to users of the latest version, and use this role to control access to the feature. Use a view to abstract the role requirement.

C. Implement a UDF (User-Defined Function) that checks the application version and returns a flag indicating whether the feature is available. Use this flag in SQL queries to conditionally enable the feature and track its usage.

D. Use Snowflake's Resource Monitors to track resource usage by different versions of the application.

E. Rely on the consumer to explicitly enable the feature through a configuration parameter, then log the feature's usage.
