Sounds like a reason _not_ to implement what you asked for:
YAGNI, if you typically run the same grep query in the same dir.

Your reason for the request was that it is a nuisance to change
directory:

FWIW, I'd suggest that Emacs command `cd' provide a reasonable
minibuffer history list: the directory names previously entered
from the minibuffer.  That is not the case currently - all
entered file and directory names are in the history.

(To change to a subdir, `cd' completion is quick.)
