Some feed readers provide a “live” OPML endpoint. Miniflux does, and Inoreader, I think, allows for it too.

Which then made me add an OPML endpoint to my Aperture—a Microsub server—install. I mean, doesn’t have to be a separate service. (Aperture, by the way, will also let you store a feed’s format and name.)
