Currently we are only bumping 1.x patch versions when bumping SDK minor versions, e.g. #11879
@brunobat recently reported a breaking change when updating 1.x patch versions. He didn't recall the exact breakage, but I suspect it may have been in an SDK incubator (alpha) artifact, which is ok to break in minor SDK version bumps, but not great to break in a patch update of Instrumentation (which bumps the minor SDK version in its bom).
