WordPress 6.9 added practical blocks including Accordion, Time to Read, Term Query, and Math, alongside blocks for comments and taxonomy data. The useful change is not simply a larger inserter. A small content requirement may no longer need an entire plugin.
Why it matters
Accordion fits FAQs and long explanations. Time to Read gives visitors a quick expectation. Term Query can build a category or tag directory from site data, while Math supports educational and scientific content that needs clearer notation.
Do not remove an existing plugin immediately. Compare the feature you actually use, then inspect the HTML, accessibility, and mobile design. The older plugin may provide analytics, controls, or compatibility that the Core block does not yet cover.
Try it quickly
Create an unpublished page containing all four blocks and apply your theme styles. Test Accordion with a keyboard and screen reader, confirm that Term Query links to the correct archives, and inspect the page at narrow widths. Remove a dependency only when the Core block replaces the real requirement.
