Comment 11 for bug 1915250

Fwiw, mysql-8.0 is also affected:

$ dpkg -c libmysqlclient21_8.0.23-3_amd64.deb|grep buildd
drwxr-xr-x buildd/buildd 0 2021-02-11 10:32 ./
[many more]

And some more:

$ dpkg -c libqt5xdg3_3.6.0-1ubuntu2_amd64.deb |grep buildd
-rw-r--r-- buildd/buildd 268440 2021-02-11 21:58 ./usr/lib/x86_64-linux-gnu/libQt5Xdg.so.3.6.0

But it seems to have stopped around Saturday, not sure if something was done on the buildds maybe?
