I wrote earlier that -P (let's use your proposed option name) should
prepend dirchache path to FPATH. In other words, -P causes any descent
autoload to try dircache part first, then follow to process fpath.

I think -P is a complete idea, as you know it comes from problems with
Zplugin, -P would solve those problems. So the idea has some real world
experience to back it up.
