Is this hook really deprecated? ( manage_{$taxonomy}_custom_column )

Question

I've been adding some data to the columns of two taxonomies in a theme I'm working on. I've hit something that's got me confused though.
I'm using this hook manage_{$taxonomy}_custom_column but the Adam Brown page on the hook says it's no longer in use. When using the hook I get no errors, so can this be true? I can't seem to find a replacement either. How can I tell if my hook, or any other hook, is deprecated?

Answer 1

manage_{$taxonomy}_custom_column is a dynamic hook, so until you are using a proper value for $taxonomy like post_tag, it would work perfectly.

Adam Brown page tells it as deprecated because it looks for exact match, while there is a change in the files so the current hook being used are manage_{$this->screen->taxonomy}_custom_column or manage_{$screen->taxonomy}_custom_column which accepts the same value whether it is post_tag or something else, and that's the reason you don't get error or warning.
