Joris Van den Bossche commented on ARROW-15250:
-----------------------------------------------
I think there was also still some doubt on the PR about whether this is
actually needed. The question is also how far we would do (eg lubridate seems
to support both ISO8601 durations
(https://en.wikipedia.org/wiki/ISO_8601#Durations) as more custom
abbreviations).
