> In some file composition, AbstractFileMergeOperator removes incompatible files. For example,
> {noformat}
> 000000_0 (v12)
> 000000_0_copy_1 (v12)
> 000000_1 (v11)
> 000000_1_copy_1 (v11)
> 000000_1_copy_2 (v11)
> 000000_2 (v12)
> {noformat}
> 000000_1 (v11) will be removed because 000000 is assigned to new merged file.
