I think what I'd like to do in the far future is when I link out to specific platforms that require some sort of munging (on my site), I'd have it link visibly to a page that represents how my site shows it before sending them all the way to the original content. It'll have proper attribution and the like, as well as a way to ask for removal from my site (in which case, I'd probably reach for a publicly archived version). I might also only enable this, of course, for sites with no hint of MF2 support, with a CTA to ask them to mark up such pages. Gotta keep plugging!
