Since no-one commented, I figure it's best to follow MLIR's lead for 
consistency. So the history rewriter has been updated to generate a 
0-parent commit and a merge:

https://github.com/flang-compiler/f18/pull/854#issuecomment-572578180

This decision can still be revisited until the merge occurs!
