When a feature is marked deprecated, it means:

The feature is in maintenance mode only. No new changes are added, including changes

related to addressing interoperability with new features.

We strive not to remove a deprecated feature from future releases to make upgrades

easier. However, under rare situations, we might choose to permanently discontinue

(remove) the feature from SQL Server if it limits future innovations.

For new development work, don’t use deprecated features. For existing applications, plan

to modify applications that currently use these features as soon as possible.

You can monitor the use of deprecated features by using the SQL Server Deprecated Features

Object performance counter, or the

and

extended events. For more information, see

Use SQL Server Objects.

The values of these counters are also available by executing the following statement:
