> After ARROW-15169 is merged, the Python--R bridge code will properly use external pointers to pass references to C API structures. The changes made on the R side will (probably) only work with the new pyarrow version. If it doesn't, it's not hard to provide backward compatibility:
> {code:R}
> pa <- reticulate::import("pyarrow")
> if (package_version(pa$`__version__`) >= "6.0.0.9000") {
>   # the new code
> } else {
>   # the old code
> }
> #> NULL
> {code}
