They're both user-controlled settings, though they default differently.
I think it's fine to leave them under the user's control.  Most systems
default to stty -istrip cs8, which means that the terminal gets eight
bits regardless of the state of input-meta anyway.  This means that the
enable-meta-key default is usually correct.
