No. You can see it in the archive[1]. Direct link[2].

So, omit “extension” from the path options, append it to search for control files, and then append the directory value (if not absolute) if it exists to look for files, and otherwise append “extensions” to find them, too. I think that makes sense.

Essentially it becomes a SHAREDIR search path.
