Yip, Steemit needs to consider they are not the only source anymore and for that matter, they are more akin to a headless CMS. Fair enough if a person posts directly to Steemit make that content work for the site but if that content is being published directly to Steempeak, or for anyone that truly wishes to own their content a self hosted site then-current practices will not work since Steemit out ranks almost anyones personal sites. If Steemit wants to be Medium.com then they can sure but have the tools and information available for authors and implement a proper way of doing things. Sure the blockchain is fancy and new but being a blogging site with all the bells and whistles is ancient by now. So they actually do not have much of an excuse to not have appropriate standards in place even more so since Steemit was just the little example let the rest go build their own thing the motto. Honestly, I just think Steem is just a shared database and Steemit has moved in and taken ownership with no consideration for others. The only way I think you can get around it right now is to get indexed by google, bing etc first then post to steem with a link back. Not sure how full content actually affects you... I tend to fall asleep when reading about SEO. Just my little 2cent rant.
