Consider un-deprecating 'category_link' and 'tag_link' filters

[SergeyBiryukov]

Background: #49738, #49755.

Some history on ​category_link and ​tag_link filters:

• [15825] / #12659 turned get_category_link() and get_tag_link() into wrappers for get_term_link(), and marked the filters as "back compat" in a comment.
• [27827] / #27505 marked them as deprecated in favor of term_link, though the ticket does not explain why.
• [46684] / #48255 used apply_filters_deprecated() on them, so developers still using them now get a notice.

I think these filters have the benefit of filtering the category or tag links without having to check the $taxonomy argument. In hindsight, it seems like they were deprecated by accident rather than an intentional decision.

There are a couple of related filters that are not deprecated:

• ​get_edit_tag_link
• ​edit_tag_link

I don't see a good reason for category_link and tag_link to stay deprecated.

Hi,

Yes, I got a notice on my blog’s Archive pages using Twenty Twenty and a bunch of plugins…
I agree it’s better to un-deprecate those two filters.
