Delete old unused files

[cmnrd]

This deletes the .obsolete, .preliminary and .less-developed subdirectories. As far as I can see, the content of these files is quite old and not up to date. I think it is safe to delete them. Please double-check.

Pinging @tanneberger as docs/.less-developed/future-proof-package-and-import-system.mdx and docs/.preliminary/import-system.mdx contain information that could be useful for the discussion on import mechanisms and syntax.

LGTM. Let's let Martin Schoeberl capture what is useful from the Patmos file. I've made a local record or the related-work file, which I do think is useful but probably doesn't belong on our website.

I think it is safe to delete them.

I can confirm these pages are not used/referenced anywhere within the website

@cmnrd I made a backup of master. So these files don't get lost.

Sidenote, git is created for this purpose, we can just git checkout files which we removed

From the website point of view LGTM

I will review this and might submit a version of this as an RFC.
