Pandoc recently added read/write support <https://github.com/jgm/pandoc/issues/9475> for "admonitions", which are a GFM construct <https://github.com/orgs/community/discussions/16925> already supported by other org-exporters, and on GH in markdown. This refcard <https://github.com/fniessen/refcard-org-mode?tab=readme-ov-file#base-admonitions> references an org #{begin,end}_{note,warning,tip,caution,important} syntax which pandoc now follows (though it does not support the extra admonitions like danger/error/etc.).
It would be nice to add org support for these 5 admonition blocks to the C-c C-, org block structure templates, and perhaps allow block face styling for these as well (ala org-src-block-faces).
