David Li commented on ARROW-16870:
----------------------------------
Yeah we should add an exception for MacOS (didn't realize that). The flag is
needed on Linux though:
https://grpc.github.io/grpc/cpp/md_doc_server_reflection_tutorial.html
If there's an analogous MacOS flag we should add it.
BTW I'm "lidavidm" (common mistake :) )
