I implemented [1] the check logic on hkml.  Many things to fix and improve in
future, but seems working at least for this series.  You can use it like below:

    $ hkml patch check --check_recipients only ./0002-mm-khugepaged-add-damon-collapse-folio-range-for-external-callers.patch
    MISSING RECIPIENTS for [RESEND RFC PATCH v2 2/5] mm/khugepaged: add damon_collapse_folio_range() for external callers
    - Andrew Morton <akpm@linux-foundation.org>
    - David Hildenbrand <david@kernel.org>
    - Lorenzo Stoakes <ljs@kernel.org>
    - Zi Yan <ziy@nvidia.com>
    - Baolin Wang <baolin.wang@linux.alibaba.com>
    - "Liam R. Howlett" <liam@infradead.org>
    - Nico Pache <npache@redhat.com>
    - Ryan Roberts <ryan.roberts@arm.com>
    - Dev Jain <dev.jain@arm.com>
    - Barry Song <baohua@kernel.org>
    - Lance Yang <lance.yang@linux.dev>
    - Usama Arif <usama.arif@linux.dev>
    - linux-kernel@vger.kernel.org
    $ hkml patch check --check_recipients only ./0003-mm-damon-vaddr-implement-mthp-aware-damos-collapse-handler.patch
    MISSING RECIPIENTS for [RESEND RFC PATCH v2 3/5] mm/damon/vaddr: implement mTHP-aware DAMOS_COLLAPSE handler
    - Andrew Morton <akpm@linux-foundation.org>
    - linux-kernel@vger.kernel.org

It is also integrated with the interactive mails list [2], so that you can run
it without manually downloading the patch files.

FWIW, 'hkml patch format' automatically adds recipients based on
get_maintainer.pl, so this check is unnecessary for hkml users.  But this will
help me reviewing patches that not formatted with hkml or other similar
scripts.

hkml has a feature [3] to monitor new mails.  Extending it to run this new
check and send mails for check failures could be one of the ways to implement
the bot.  I'm not planning to do that by myself, though.  I will run the check
only for patches that look interesting to me, for now.
