This has popped up already in the lists in the past.

This kind of thing is heavily application-dependent.  For example, you
would likely not care if an operator, who has newly-joined the team in
charge of the maintenance of this data, drops unfortunately a table
which includes logs from 10 years back, and you would very likely care
about a table dropped which has user's login data.  My point is that you
need to carefully design the shape of the configuration you would use,
so as any application's admin would be able to cope with it, for example
allowing exclusion filters with regular expressions could be a good idea
to dig into.  And also you need to think about it so as it is backward
compatible.
