The purpose of the feature freeze is not to release half-baked
stuff.  If we introduce this variable in 21.4, then it should remain
with upwards-compatible semantics also in future versions.  If we
find that this feature is likely to be replaced by something
different in future versions, we should leave it out completely for
now.

There is no point in introducing a feature that will only exist for a
single release.
