Review Comment:
Regarding schema evolution (like field rename), users have to adjust the
name reference. this is also applicable to filter expressions or column
projections. Users typically reference fields by name.
In another thought, I am also not sure we need to expose this to users
directly. The only usage of column stats is the watermark alignment. we will
need to expose `enableWatermarkAlignment(String watermarkField)` anyway. there
is probably no need to expose this directly, at least not yet.
