But that's the problem.  Why bloat 'ls' to do something that 'find' can
already do?  For that matter, even if we added it to 'ls', it would be
quite some time before those changes percolate to your distro, and you
wouldn't be able to rely on that extension being present on every
machine; while you already have a working solution with 'find' present
on any machine you want.

The whole idea of Unix tools is to do one thing and do it well; it is
'find' that is good at locating files that meet a particular criteria,
so bloating other tools to duplicate that is not going to be worth the
effort.

You can always create a shell script (or alias) that bundles the proper
find arguments into a much more compact name that you find easy to
remember.  But I still don't see the point to bloat ls (which already
has too many options) to do something that find can already do.
