| * |
| * You cannot even change them in sync, since newer module must work on older Android T releases. |

| * You could with difficulty, uprevs of the bpfloader, api detection logic in mainline, etc, |
| * change this in Android U or later, but even that is a very bad idea and not worth the hassle. |
