Package: coreutils Version: 8.32-4+b1 Severity: normal Dear Maintainer,
It appears drain/-drain is special, in that, unlike all operands,
it does /not/ prevent default output and it does /not/ exclude -a/-g:

This is undocumented, and, indeed, directly against the usage string:
Usage: stty [-F DEVICE | --file=DEVICE] [SETTING]...
or: stty [-F DEVICE | --file=DEVICE] [-a|--all]
or: stty [-F DEVICE | --file=DEVICE] [-g|--save]
I assume this is an oversight.
Best,
