I guess you're talking about the first line of the commit message, which is interpreted by various
tools as a summary.

We already have this as a commit message footer, like Change-Id, Reviewed-on, Tested-by, etc.
Everybody can easily add a "Sponsored-by" "field". No problem to parse this with any tooling I
guess, if we go with a simple "<key>: <value>". We can suggest some default keys, which are used by
our tooling. The Linux kernel mentions some in their Documentation/process/submitting-patches.rst.

Just please don't start putting more stuff in the first commit line, which doesn't describe
technical functionality of the patch.

I would actually move the "tdf#..." to a "Fixes: tdf#12345" and also allow multiple of these
entries. Maybe also a "Regression-from: <commit id>", so it's easier to catch multiple patches when
backporting fixes. As this is managed by humans, it won't be perfect but better then nothing.
Formats like the one used by debian/control even allow multiple lines per key by indention, but we
should be fine without, as the rest of the commit message is free text.
