We've been supporting something like this in b4 for a while now, but we use prerequisite-* trailers (not tags) and always expand that into prerequisite-patch-id, since that's the only format documented by git itself. E.g. here is an example of a series using prerequisite-change-id: https://lore.kernel.org/b4-sent/20250526-sip_svc_upstream-v3-0-6a08a4502de3@altera.com/ Here's another one using prerequisite-message-id: https://lore.kernel.org/b4-sent/20250514-ipq5018-pcie-v10-0-5b42a8eff7ea@outlook.com/ The documentation is here: https://b4.docs.kernel.org/en/latest/contributor/prep.html#working-with-series-dependencies I'm not sure "Depends-on:" as an actual commit tag will be accepted by the kernel community, because it's information that is only useful during pre-commit stages. However, if it's passed along as a cover letter/first patch trailers, we can recognize it as an alternative for "prerequisite-message-id". -K
