[I] [Python] `Array.from_buffers` docs should mention safety issues [arrow]
pitrou opened a new issue, #49717:
URL: https://github.com/apache/arrow/issues/49717
### Describe the enhancement requested
The docstring for `Array.from_buffers` (and similar methods on subclasses, e.g. `StringArray.from_buffers`) should explicitly mention that the caller is responsible for passing valid Arrow data (or calling `validate` on the result), otherwise they could encounter crashes when using the result.
### Component(s)
Python

Hi @pitrou, I'd be interested in contributing to this issue if it's still available.
I'd update the `Array.from_buffers` documentation and the relevant subclass methods to explain the caller's responsibility for valid buffer layouts and recommend validation where appropriate.
Would this be a useful contribution, and is there any particular wording or scope you'd prefer?
