Antoine Pitrou commented on ARROW-14904:
----------------------------------------
bq. Apologies if I'm reopening a debate that's been settled, but just because
appending isn't supported on all filesystems, why does that mean we can't allow
it on filesystems where it is supported?
We can, it's just that it's less useful :-) Nobody opposed when we started
deprecating it, but we can un-deprecate if desired.

> This would be a match for the {{readr::write_csv()}} {{append}} argument:
> boolean. If {{FALSE}} will overwrite existing file. If {{TRUE}} will append
> to existing file. In both cases, if the file doesn't exist, a new file is
> created.
