Back in #13280 I had proposed to add SubplotSpec.add_subplot() (adding to the figure to which the gridspec is bound), which would allow one to write, here,\r\n```\r\nspecs = fig.gridspec_mosaic(...)\r\nd = {\r\n    \"foo\": specs[\"foo\"].add_subplot(projection=...),\r\n    \"bar\": specs[\"bar\"].add_subplot(projection=...),\r\n    ...\r\n}\r\n```\r\nbut that idea got shot down back then and even if we decide not to revisit it, even the first form would be nice to have.\r\n\r\nThoughts?\n\n### Proposed solution\n\n_No response_","author":{"url":"https://github.com/anntzer","@type":"Person","name":"anntzer"},"datePublished":"2022-11-30T22:25:45.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":13},"url":"https://github.com/24571/matplotlib/issues/24571"}
