Per and as promised in my reply to issue 796 (comment on #796), it may be of some value to add Micropub as a generic Bridgy Publish destination, that is, Bridgy Publish acting as a Micropub client to post to Micropub servers.
One possible use-case would be Bridgy Publish to silo.pub, and thus potentially enabling use of Webmention to Bridgy Publish as a method to gain access to any additional destinations that silo.pub itself supports. I.e.:
indiewebsite --Webmention-> Bridgy Publish --Micropub-> silo.pub --❄️API-> silo
