What makes you think this?

In login.postinst, we have:

        # Create subuid/subgid if missing
        if [ ! -e /etc/subuid ]; then
                touch /etc/subuid
                chown root:root /etc/subuid
                chmod 644 /etc/subuid

(strangely indented, admitedly....but unless I'm missing something
obvious, it is unconditionnally run)

That code probably somes unchanged from the patches that have been
proposed, indeed.

And, well, on my system, /etc/subuid and /etc/subgid were indeed
created when I manually installed the new login package.
