Please don't update package not for buster to unstable
I see you uploaded golang-github-mattn-go-isatty/0.0.7-1 and
golang-golang-x-sys/0.0~git20190412.9773273-1 to unstable. I'm sure
release team won't unblock these new versions for buster.
This breaks the build-rdepends, if they need to fix RC bug in buster.
Take aptly for example, I upload a fix for buster, now it can't
migrate because it should migrate after golang-github-mattn-go-isatty
Maybe we can use testing-pu, but the release team strongly prefer
changes that can be done via unstable instead of
PS, it's not about packages not in testing.
