bq. Is this an answer to your question?
Of course, thank you. So it seems the fix (if someone wants to fix the issue
and produce reliable Windows wheels for PyArrow) should be to bundle the CRT
DLLs with the wheel. It used to be simple as there were just two such DLLs
({{msvcrt}} and {{msvcp}}). Nowadays, there are several of them.
Alternatively, just mention that people have to install the redistributables
separately. They're useful for a ton of other software anyway.
