Ok, it seems that it would be hard to implement it in a way it would be useful. I already use sync via OneDrive and regular auto-backups of this folder (with LocalState folder sync to that OneDrive folder via FreeFileSync) to my NAS. I just also wanted to have full backup in single .msb file. In a rare (and not seen so far) scenario I need to make quick installation of MS into new device and quickly load my whole library, one file seems to be better and easier.

I agree that a full MSP backup is useful. I only doubt that implementing a reminder or starting the backup automatically in MSP makes sense. It's so easy start the backup manually and keeping in mind when to do so compared to making it work in MSP so that everybody is happy with the way it works.
