That isn't the case:
https://www.gnu.org/software/emacs/manual/html_node/elisp/Magic-File-Names.html
states clearly "The handler function must handle all of the above
operations, and possibly others to be added in the future."

That is also not the case. If there's no handler, setting
:file-handler to t has no effect. That's the same as for
start-file-process, which calls start-process if no handler is found.
