Oops, really shouldn't try to answer questions for the master ;-) Your advice is the far more elegant way of doing it, of course.

I normally use only the scanner myself for cleaning romsets or for updating.

For sharing I would personally prefer creating a clean copy from the scratch using the rebuilder rather than directly sharing my rom directory (keeping a backup in case something goes wrong, issues with access to files currently kept open by clients, excessive hard drive usage, you name it). Of course you can just make a copy of your directory and scan it the way you described. However, if you have to torrentzip the romset afterwards, time spent on CMPing a romset is not really an issue.

Since you have made your tool so versatile, I found that quite often you have choices to do the same thing different ways, and then for me it all comes down to personal preferences.

Just out of curiosity and correct me if I am wrong, isn't the scanner generally using the same internal functions as the rebuilder? What difference does it make then using one or the other? I suppose sets, which already correct, will be ignored rather than rebuilt and it will save you a lot of time if you intend to upgrade from fairly complete romsets.
