### Describe the enhancement requested Concatenation of a single array can be used (recommended? where?) as a memory compaction utility, since it produces a deep copy of the array. This should be better documented and should be tested, since the hot path of passing a single array through unchanged is tempting. (alternatively, Array::DeepCopy might be provided) See also discussion in PRs: - https://github.com/apache/arrow/pull/37792#discussion_r1336058944 - https://github.com/apache/arrow/pull/35345#discussion_r1333197326 ### Component(s) C++ -- This is an automated message from the Apache Git Service.
