Neal Richardson commented on ARROW-14904:
-----------------------------------------
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?
> Do we have to emulate everything that's provided by another R library?
Absolutely not, and likewise with pandas or any other package. But for every
feature they have, there's a reason it exists, and we should evaluate whether
it seems like a good reason--or, at least decide to wait until someone asks for
it.

> 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
