The project team considered this approach and decided that ls is the
appropriate utility to list file attributes whether those attributes be
one of the three original timestamps, the file mode bits, or ACLs
already handled by ls or the new creation time timestamp and the new
extended system attributes.

There is no incompatibility.  If lsattr proves to be popular, there is
no reason why this version of ls and lsattr cannot coexist.  And, the
output from any ls command in a script today is unchanged by this
proposal.  The ls output changes only if one of the new options appears
when the command is invoked.
