filepath is fairly large.  canonical-path and friends, together, are tiny.
they are not addressing the same set of issues, regardless.

again: canonical-path does not do existence checking.  it is not meant to. 
it is intended to create localised canonical forms of a path in any 
representation as an aid to installation and naming portability.
