infrastructure: use of merge queues?

Context: RustCrypto/SSH#469 (comment)

Now dependabot deprecated the merge command, which I used to merge a dependency bump after CI passed (reducing the load, especially on long CI runs (set the auto merge, and move on, no need to check back in 20-30 minutes)), what would be the alternative?

The GitHub blogpost (https://github.blog/changelog/2025-10-06-upcoming-changes-to-github-dependabot-pull-request-comment-commands/) is as useless as it can be.
Their alternative is to use the gh command line, which does not really have that feature?!.

My understanding is that the only option from then is the use of merge queues. Is there any other option?
I believe this something only someone with admin access on a repository can deploy, any way I can help?

Seems fine to me
