I haven't checked yet what's needed. However, there are several
incarnations of `expand-file-name' implementation in Tramp, namely

--8<---------------cut here---------------start------------->8---
grep --color=auto -nH --null -E 'defun.+handle-expand-file-name' *.el
tramp.el3393:(defun tramp-handle-expand-file-name (name &optional dir)
tramp-gvfs.el1137:(defun tramp-gvfs-handle-expand-file-name (name &optional dir)
tramp-sh.el2683:(defun tramp-sh-handle-expand-file-name (name &optional dir)
tramp-smb.el736:(defun tramp-smb-handle-expand-file-name (name &optional dir)
tramp-sudoedit.el346:(defun tramp-sudoedit-handle-expand-file-name (name &optional dir)
--8<---------------cut here---------------end--------------->8---

Best regards, Michael.
