We may want to add an audit pass which prints a warning if the path of a file within the prefix is longer than ~200 characters (consider that files in artifacts will placed be in <depot>/artifacts/<hash>/).
We have discovered the hard way (https://github.com/JuliaPackaging/Yggdrasil/pull/4720) that file paths on Windows can't be longer than 260 characters by default, unless users change this limit: https://docs.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=powershell.
