No, workerd and its semantics are not exclusive to Cloudflare infrastructure. People really do run it in production without using Cloudflare at all (I really wish I was allowed to say who because one of the users is hilariously ironic...).
Ryan's and Bert's core focus at Cloudflare is going to be making the self-hosting story better.
This was emphasized in the blog post: https://blog.cloudflare.com/deno-joins-cloudflare/

I believe they are. You may be able to run workerd, but you can't run D1 (Sqlite alternative), you can't run KV or Queues (please correct me if I'm wrong).
All those are primitives that already exist in the non CF world: KV can be easily redis/memcached. Queues, Kafka and so on. I believe that a system that reuses those would be stronger.

Ok, this peaked my curiosity. Would be great if you could share it!
Details remain to be worked out, but part of the goal of the project is to make all these interfaces plugable with reference implementations that can sit on common infrastructure.
In fact, celld has already done a lot of this.

You'll have to find me in person over drinks somehow. ;)
that's an interesting reflection on the nature of open source - in theory the source is there and "the community" could conceivably continue development. especially in the case of something like deno where the people most motivated to keep it alive are already programmers. but the reality is that however distributed an open source project is in theory, in practice it needs a single entity to steward it, otherwise it will die.
hopefully that single entity can be a consortium of companies invested in using the runtime, sort of like opentofu recently.
I believe this is very unlikely to happen. If the founder (Ryan) was involved in it or it have strong market position, it would have strong chances.
Now, is a kingdom without a king and without strong companies to steward it forward. I hope to be wrong though!
But that points to an important aspect of the platforms-game: The interface between the runtime and everything else should be standardized, to support true pick-and-choose.
This have a similar analogy with browsers. Back then when Internet Explorer was the only supported browser, the websites were not evolving as fast. When Firefox pushed it forward and then Chrome, customers won (better and faster sites).
