Micro.blog works in a way somewhat similar to that. A very Twitter-like timeline is effectively centralized, but behind the scenes everything is built on open standards like Atom, webmentions, etc., and your "account" is actually just your own blog -- although that blog can be hosted (for $5/month) on Micro.blog itself. It has a web interface a lot like Twitter's, a first-party client and several third-party clients, and in most respects just a much nicer user experience than Mastodon.
On the flip side, Micro.blog has a very different culture than Mastodon seems to[1], makes some very opinionated choices that many people might not agree with (e.g., there's not only nothing like retweets, but likes and even followers aren't public information), and of course, the easiest way to use it costs money.
[1]: Yes, I know there are lots of instances with different cultures, but there really is a kind of left-wing anarchist vibe across a lot of Mastodon; it's hard to explain if you haven't experienced it. Micro.blog comes across as generally more gentle, very conversational, and more Gen-X than millennial, if that makes any sense. (If it doesn't, sorry. Again, hard to explain if you haven't experienced it.)
