I'm on board with a new named format that selects the desired defaults
instead of requiring the user to know and change them all manually.
This seems to me like a "list" format. Implying each row is a list entry.
Since we have tables the concept of list would likewise reasonably imply a
single column.
Since newlines are special, i.e., record delimiters, "plain" thus would
remain misleading. It could be used for a case where the entire file is
loaded into a new row, single column.
