> When deserializing a \{{Columns}} subset via bitset membership, it is trivial 
> to add a modest probability of detecting corruption, by simply testing that 
> there are no higher bits set than the candidate \{{Columns}} permits.  This 
> would help mitigate secondary problems arising from issues like 
> CASSANDRA-14568.
