Automatic configuration and database backup? sort of gets at this, and links to support requests in the area. There might also be feature requests in Issues on GitHub (along with lots of open bugs to solve).
The database side of above request is probably harder, because the database can become very large. Fortunately, database Recreate is better in 2.0.5.1, so backup of database in its entirety has less gain.
Add ability to import backup configurations from command-line #3595 has gotten its developer at least somewhat more familiar with import code. I don’t know about export, and the web UI is also not known.
I’d note that recent emphasis has been on reliability. If that push ends, maybe features can be added…
