Why do we get so many different looking dialogs from the same task?

And that's not counting the Bad Filename, Rename dialog, Preview dialog, Preview detected warnings prompt...
Couldn't XY do a preliminary check.
If it finds any issue pop up a modified preview dialog which lists all of the items and also prompts to proceed (within the same dialog).
If the user chose to proceed it could still show the summary at the end but ideally the header of that dialog would include the text from/similar to the status bar: "# items renamed. The following # left untouched."
The status bar would also still show that text, which would be redundant, but I think that's a cleaner solution than only showing it when XY is 100% successful.
If the user manually previews before renaming then nothing should change from how it is now. Preview Dialog->Warning Prompt->Summary.
