Sparrow: C++20 Idiomatic APIs for the Apache Arrow Columnar Format

  // You are responsible for releasing the structure in the end
  arrow_array.release(&arrow_array);

This doesn't look like RAII. How is this idiomatic for C++20? Why do you have to pass a pointer to "this" again as an explicit argument.

RAII predates C++98, I was already used to it in Turbo C++ for MS-DOS, and is pity we need to keep advocating for it as something extraordinary.

This doesn't have anything to do with what they said, they didn't say RAII was new.

Might be misunderstood by others not skilled in C++ when reading,

You can try to be insulting if you want but if you could explain the connection I think you would have already.
