I'm not sure I consider it "special", but since it reports hints about the
build/test configuration combinations (i.e. "this test failed probably
because CONFIG_FOO is missing"), it seemed trivial to also include the
specifics of the version and arch.

Right, I completely understand that. If you really want it gone, I
will rip it out; it'll just make it more time consuming to analyze some
CI reports.

Completely agreed, and I've been _also_ been spending my time sending
patches[1] to CI tooling too, trying to solve this from both sides. But
not all CIs have the source for their machinery open for patching. :(
