Personally I think that's a fine goal to aim for. I'm not sure what
"to be considered a relational database" means but I consider a bug
whenever there's a case where this isn't true. It may be a bug that we
don't have a good solution for or a bug that's too minor for the
amount of effort it would require but it's still not right and if we
found a solution that we were happy with we would definitely want to
fix it.
