-------------------------------------------------------------
[~mreutegg] - back then, there simply was no need, as there simply was no RDB
specific {{VersionGCSupport}}. When I introduced it, I worked around the issue
by using constraints on {{_id}} instead.
I'm prepared to change the DB schema, but it will require a bit of work with
respect to compatibility and migration. I wouldn't rush this until we have
proper test coverage for it.
