Well, SBCL and ECL do not have that problem, AFAIK. But TRUENAMIZE also
seems to be used with files, not directories, from what I could gather
during the debugging of ASDF. I would abstract those calls into a function
PROBE-FILE-AND-DIRECTORY and use PROBE-FILE internally in this function. The
purpose would be clear and sensible  implementations might profit from that
-- maybe the terrible startup times for ASDF might be decreased this way.
