I fully second your idea! However, as a workaround, I recently found www.ukeeper.com. There you can create a Bookmarklet (or save the resulting Javascript Code to a new bookmark in Brave browser) to have sent from Brave directly to your mailbox a clutterfree version of any website. From there I use the MailButler plugin for Mac Mail to save the message as Evernote (but you could also simply forward it to your Evernote mail adress, with tags and all the rest).
