I have no plans to add checksums, EGIS, sorry... checksumming a million files every time you back up seems impractical and time consuming. Keeping multiple backups of any important data is a more reasonable approach, I think, on a redundant device (e.g. RAID, Drobo, etc).

You can certainly back up selected files by writing a copy script if you want. I encourage you to back everything up, though.
