I know those questions are probably rhetorical, but to answer them anyway:
> > Nice syntax
> Is it though?
The most common alternative is to use a backslash at the end of each line, to create a line continuation. This swallows the newline, so you also need a semicolon. Forgetting the semicolon leads to weird errors. Also, while Docker supports comments interspersed with line continuations, sh doesn't, so if such a command contains comments it can't be copied into sh.
There heredoc syntax doesn't have any of these issues; I think it is infinitely better.
(There is also JSON-style syntax, but it requires all backslashes to be doubled and is less popular.)
*In practice "&&" is normally used rather than ";" in order to stop the build if any command fails (otherwise sh only propagates the exit status of the last command). This is actually a small footgun with the heredoc syntax, because it is tempting to just use a newline (equivalent to a semicolon). The programmer must remember to type "&&" after each command, or use `set -e` at the start of the RUN command, or use `SHELL ["/bin/sh", "-e", "-c"]` at the top of the Dockerfile. Sigh...
> Are the line breaks semantic, or is it all a multiline string?
The line breaks are preserved ("what you see is what you get").
> Is EOF a special end-of-file token
You can choose which token to use (EOF is a common convention, but any token can be used). The text right after the "<<" indicates which token you've chosen, and the heredoc is terminated by the first line that contains just that token.
This allows you to easily create a heredoc containing other heredocs. Can you think of any other quoting syntax that allows that? (Lisp's quote form comes to mind.)
> Where is it documented?
The introduction blog post has already been linked. The reference documentation (https://github.com/moby/buildkit/blob/master/frontend/docker...) mentions but doesn't have a formal specification (unfortunately this is a wider problem for Dockerfiles, see https://supercontainers.github.io/containers-wg/ideas/docker... instead it links to the sh syntax (https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V...), on which the Dockerfile heredoc syntax is based.
(Good luck looking up this syntax if you don't know what it's called. But that's the same for most punctuation-based syntax.)

A solution for implementing efficient and consistent software delivery to Kubernetes facilitating best practices.Project mention: Is there a CD solution that can be (painlessly) fully automated between stages? | reddit.com/r/kubernetes | 2022-09-08
I am looking as well for this kind of tool. I just took a look today by exploring the CNCF landscape this tool : https://werf.io/ , I haven't used it, but it seems to take care of painful stuff like automatic versioning for example. (If someone here tried it, I will be happy to listen to your feedbacks)
A build flow tool for Docker.
Program to reverse Docker images into DockerfilesProject mention: Reverse Image | reddit.com/r/docker | 2022-10-28
https://github.com/P3GLEG/Whaler <-- that should do what you're looking for. It depends on the image having been generated using a standard Dockerfile approach, but that should work for most images.
