This should be doable, and doesn't come anywhere near the "rewrite"
job.  You just need a way of blocking the output from the shell, and
then use Emacs commands to kill it.

You didn't try Emacs 29 yet, did you?

Concurrency can help you keep reading messages while Gnus refreshes in
parallel, but it won't easily help you refresh faster, unless someone
comes up with a way of collecting the update in parallel chunks (in
which case they should be able to do that today with the emacs-async
package, I think).
