This might be a coincidence involving the timestamp of /System/Library/Extensions inadvertently getting modified by something else in my installer script, in which case the answer to the question is definitely 'no'.
I did some more testing, and now I am sure that my install scripts were inadvertently touching /System/Library/Extensions. So, if you want the kext cache updated, touch /System/Library/Extensions explicitly, just to be sure.
