Personally, I have the backups covered by doing backup of the profiles themselves to backup media as well as the %WEEKDAY% variable in the backup destination making several backups per week. Myself, I would want the CLEANUP checkbox more than any "protection" that NOT cleaning the backup directory affords.
I've updated my OS, PC and reimaged too many times since I started using SB years ago, and had to reinstall SB and been caught by this a few times. I restore the profiles - and restore all the other profiles that I had deleted weeks, months even a year or better before. I have quite a nested "mess" of profiles that I change and update regularly.
I would say offer the CLEANUP function and make a stern popup that using it will delete all the backup folder profile backups - much the same type of warning that the file and folder deletion profile options do in SB itself when chosen when defining a sync profile.
