I think the main problem here is that some implementations (notably CLISP) differ between files and directories, so PROBE-FILE cannnot be used to probe files AND directories.

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.
