Complaint against "Synchronize folder ..."

I didn't call this a bug... but do you think I should?

If an image in a folder under Folders in LrC is replaced with an image by the same name, and then Synchronize Folder... is picked, LrC discovers that the metadata has changed and puts the exclamation point on the image.  When that is click and the new data pulled in from the disk, the image itself is not updated.  LrC knows the file has changed but assumes the image is the same image.  To me, that is just silly.

The work around is to delete and then re-add the image.

I hit this because I'm doing a weird publishing chain up to SmugMug.  I want to put a name plate on each image for a particular gallery I have on SmugMug.  My current (awkward) process:

1. Publish the images to my Hard Drive (publish -- not export so only the files that change are updated)
2. go to my Terminal app and run a script which creates new images that have been modified (via ImageMagick)
3. Import those images into LrC
4. Publish these new images up to SmugMug via their plug-in.  I did the above originally.

Now, for updates, it is even more awkward:

1. Same as above
2. Same as above
3. "Synchronize Folder..." but this often just flags the updated images that the metadta has changed
4. Delete those images
5. "Synchronize Folder ..." again
6. Publish on the SmugMug folder to push the new images up to SmugMug.

It would be nice if steps 4 and 5 was just to update LrC from the data on the hard drive instead of the delete and add process.
