   Another one `impl Array for T` example here 
https://github.com/GreptimeTeam/greptimedb/blob/e0285209cb62b398ce89a033a1101991d4a28b27/src/promql/src/range_array.rs#L228
 . It wraps a dictionary array into a matrix-like structure.
   
   Despite whether this impl is reasonable, or has a better alternative, 
`Array` is one of the biggest abstractions exposed from `arrow`. Many 
downstream lib like datafusion only accepts `Array` (record batch), this 
sealing also removes a large hack point to play around with data representation 
and computation. And adding a new implementation of `Array` to this arrow 
library is a hard long journey (like variant array) or not even acceptable 
(like range array for a specific usage). IMHO, this breaking is shipped too 
fast, and on a minor version.
