patchfoo doesn't use ssb-markdown, it uses ssb-marked. same for ssb-viewer and git-ssb-web. patchfoo and git-ssb-web edit the renderer objects to customize the rendering output, and git-ssb-web edits the lexer rules to linkify git object ids. so these won't be able to make use of updates to ssb-markdown as is. ssb-viewer might be the easiest to change to use ssb-markdown - i'm not sure. there is an update to ssb-marked %EnbxTha... that makes it linkify more protocols, but in a quick test I didn't it see it change how the post %HhkEF4y... was rendered. That said, I value compatibility of rendering, so if ssb-markdown is linkifying these then I will probably want to too.
