Jonathan Keane commented on ARROW-16047:
----------------------------------------
I created this ticket as a (possible) follow on and for discussion about how
widespread this behavior is + see if it's feasible to do this in C++.
If you're still interested in digging more into the C++ code here, feel free to
assign this ticket + send a PR [~ateucher] (but no pressure!).
