In dired, which basically does that.

It doesn't now, but that's only because it's implemented that way.

Well...  no, not more than usual.  You can delete a non-Tramp file from
an encrypted file system, and have the Trash on a non-encrypted file
system, and that would be the same flaw.  Whether Tramp is involved or
not is orthogonal.  (Except as an efficiency thing.)

Neither doc string says anything about remote files?

Directory for ‘move-file-to-trash’ to move files and directories to.
This directory is used only when the function ‘system-move-file-to-trash’
is not defined.
Relative paths are interpreted relative to ‘default-directory’.
If the value is nil, Emacs uses a freedesktop.org-style trashcan.

---

Move the file (or directory) named FILENAME to the trash.
When ‘delete-by-moving-to-trash’ is non-nil, this function is
called by ‘delete-file’ and ‘delete-directory’ instead of
deleting files outright.

If the function ‘system-move-file-to-trash’ is defined, call it
 with FILENAME as an argument.
Otherwise, if ‘trash-directory’ is non-nil, move FILENAME to that
 directory.
Otherwise, trash FILENAME using the freedesktop.org conventions,
 like the GNOME, KDE and XFCE desktop environments.  Emacs moves
 files only to "home trash", ignoring per-volume trashcans.
