Regarding https://letsencrypt.org/2020/12/21/extending-android-compatibility.html From what I understand, the cross sign from DST Root CA X3 (expiring soon) being introduced into the new chain for Android compatibility will break clients using openssl 1.0. Can anyone confirm this?

Expiring trust anchor, openssl 1.0
