There could be file name handlers, which have an own implementation of
file-readable-p for local files.

file-remote-p returns information about the *file name*, and not
necessarily about the file: "Can the file name be used literally on the
local host?" I believe this meaning shall be kept, for example, it is
needed to determine whether a file name must be trimmed when used as
argument of process-file and alike.

The new function you are looking for is file-mounted-p or so.
