One problem is… when you want to allow a blocked domain. It can be time consuming and confusing trying to track down which one of those things is actually stopping you.
I admin around three hundred linux servers and this is one of my most common tasks - although I use -shc as I like the total too, and don’t bother with less as it’s only the biggest files and dirs that I’m interested in and they show up last, so no need to scrollback.
When managing a lot of servers, the storage requirements when installing extra software is never trivial. (Although our storage does do very clever compression and it might recognise the duplication of the file even across many vm filesystems, I’m never quite sure that works as advertised on small files)
