That's indeed much simpler, but makes it impossible to preserve
attributes for files that have special handlers. For example, Tramp
currently preserves the SELinux context for remote SSH files by getting it
from the local file via the C API and reapplying it remotely using the
`chcon' utility. See `tramp-sh-handle-set-file-selinux-context' in

Whether or not that is a desirable feature to have is a matter of taste,
I suppose...
