Description

Re-adding a dropped column with an incompatible kind (dropped regular re-added as static, or dropped static re-added as regular) can ultimately result in corruption (see CASSANDRA-14843 for more context). In 3.x, unfortunately, we don’t persist enough context when dropping a column. In trunk, however, we do, and it’s trivial to forbid this operation, as we should.
