It would be great to have such feature.
Just some pro's of this:
1) administrator can choose between config versions for the next startup.
2) There will be no more problems with some hidden configuration inconsistency.
3) No more reset-configuration. It will be obsoleted by this.
From my point of view it seems like You already have a very good position for this.
The "export compact" which is now the default seems to be ready for this.
Do You have such plan already ?
This will move Your excellent product to even better position among competition.
