There's another dimension to this, that storage is so cheap that being wasteful with it isn't really disincentivized. I know for example at work of a portal that accepts uploads of large files from external clients that stores both the initial upload and every subsequent transformation of the file (of which there are 4-6) permanently. It's extremely useful for debugging, as one of the bits of metadata we shove on the zip archive is the git hash of the code that was running, so it's trivial to pull down any failed step and diagnose what happened.

We are using 4-6 times as much storage as we need to, and these are often not small files (on the order of 100 MB - 5 GB, several dozen times a day) but fixing this overuse is so far down the priority list that I don't think it survived the great Jira purge of mid-2024.
