Hello!
Rust, https://www.rust-lang.org, has additional files that have file names ending in .crate. The file command says they are GZipped. So I created a hard-link file.gz from a crate file and looked in GNU Emacs 27.2 into it. It looked like a TAR file, so a CRATE file must be a GZipped TAR file:

Could next version of GNU Emacs support this for dired-mode/jka-compression-mode?

I've added this to Tramp archives. That is, if you have a file "/path/to/file.crate",
open it with "C-x C-f /path/to/file.crate/" (the trailing slash matters).
Works on GNU/Linux systems only.
Pushed to Emacs master. Will also be part of Tramp 2.6 on GNU ELPA, but
this isn't ready yet for distribution.

Just made a test: adding this file extension as belonging to tar-mode into auto-mode-alist isn't sufficient! The archive is opened, but it is close to nonsense, a one-liner, that is displayed. Alright, I'll dig a bit deeper…
Recently I received the message that GNU Emacs 28.0.90 is out. Is the time already too short to add this particle?

Likely yes (but it is up to the maintainers to decide). Perhaps it could
be added after the release, for Emacs 28.2.

While trying to compile GNU Emacs 28.0.90 I patched it, and adding the addition to auto-mode-alist GNU Emacs 28.0.90 could easily open CRATE archive files and walk me though the archive members:

It worked for me to interactively edit jka-compr-compression-info-list to contain
["\\.crate\\'" "" "" nil "decompressing CRATE archive" "gzip"
("-c" "-q" "-d" "-S crate")
t nil "\x1f\213"]
and to augment with
(add-to-list 'auto-mode-alist '("\\.crate\\'" . tar-mode))
For me creating a CRATE archive is not important, I just want to know what is inside. I even do not know whether there is a way to create a TAR archive in dire-mode…
