It was a journey from not /requiring/ -o acl to use acls and
making it the default, to ultimately deprecating the noacl option.

The hope was that over the many years of the transition, anyone
who needed the old behavior would speak up.  :)

You could always compile without CONFIG_EXT4_FS_POSIX_ACL if
you're really concerned about it.  That's build time, not a
per-filesystem switch, of course.

If you have data to show that the inability to turn it off is
harmful, please share.

Thanks,
