> Since we have a bit of a messy Filter API with KeyValue vs Cell reference mixed up all over the place, I recommend cleaning this up once and for all. There should be no {{KeyValue}} (or {{kv}}, {{kvs}} etc.) in any method or parameter name.
> This includes deprecating and renaming filters too, for example {{FirstKeyOnlyFilter}}, which really should be named {{FirstKeyValueFilter}} as it does _not_ just return the key, but the entire cell. It should be deprecated and renamed to {{FirstCellFilter}} (or {{FirstColumnFilter}} if you prefer).
> In general we should clarify and settle on {{KeyValue}} vs {{Cell}} vs {{Column}} in our naming. The latter two are the only ones going forward with the public API, and are used synonymous. We should carefully check which is better suited (is it really a specific cell, or the newest cell, aka the newest column value) and settle on a naming schema.
