Emacs doesn't delete “files” here, it deletes “packages”.  Yes,
packages are just a bunch of files in the end, but conceptually a
package is not just a plain bunch of files.  It is a complex opaque
data structure providing Emacs Lisp code, with some complex
management/activation logic behind.

For this reason, a package can't be treated as a plain directory with
files.  For instance, restoring a package from trash doesn't restore
the package for any running Emacs session, simply because "package.el"
doesn't know about it.

Also, "package-delete" may be called in situations other than an
explicit user request.
