That ship sailed long time ago. Now, switching back to <object> will be a breaking change that should be justified. Mind that we use "img" tag for all images, not just svg. For now, you are just pointing that <object> will inherit CSS of the page. But there will be downsides you mentioned, like absence of alt attribute (which is a big deal - we do not want to compromise accessibility for blind users - see https://orgmode.org/list/CAJcAo8uTOpEazLNCr0t1kFqPGTLz=G=adnklhuo1-ura8-m...@mail.gmail.com or https://list.orgmode.org/orgmode/87czew3w5l.fsf@localhost/ ) Also, https://www.w3schools.com/TAgs/tag_object.asp explicitly recommends against <object> for images in favor or <img>. Finally, I can see that there are ways to use CSS on img+svg: https://blog.union.io/code/2017/08/10/img-svg-fill/ > - For Org to extract and embed the SVG means more things that can break > (though I admit that it can be made a lot less fragile than the > #+INCLUDE hack) and when they do break, it's an Org problem.

But some people do want embedding to make html self-contained, if not for CSS. Note that I am inclined to accept the patch for reasons different from the motivation of the patch author. Especially, if the patch gets extended to allow embedding raster images as well. > - Readable, uncluttered HTML is nice; huge, unreadable stretches of SVG > aren't. Sure, if users want uncluttered HTML. Some users do. Some wants the opposite. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
