Is cq:actionConfigs deprecated?

cq:actionConfigs seems like a useful approach for some work I need to do. This page https://dev.day.com/docs/en/cq/current/javadoc/com/day/cq/wcm/msm/api/ActionConfig.html lists a Java class of that name as being deprecated, but this page https://dev.day.com/docs/en/cq/current/developing/components.html doesn't say anything about that. Is the functionality deprecated? Is there a replacement approach for getting this functionality? Thanks
