read_feather and write_feather exist, and there is also write_arrow. But no read_arrow.
Some questions (which go beyond just R): There's talk of a "feather 2.0", i.e. "just" serializing the IPC format (which IIUC is what write_arrow does). Are we going to continue to call the file format "Feather", and possibly continue supporting the "feather 1.0" format as a subset/special case? Or will "feather" mean this limited format and "arrow" be the name of the full-featured file?
In terms of this issue, should write_arrow be folded into write_feather and there be an argument for indicating which version to write? Or should the distinction be maintained, and we need to add a read_arrow() function?
