The flag keeps the line zero entries in the line table by default and when calculating ranges it is probably safer to keep the original behavior.
Although the DWARF format has the ability to describe the split address ranges, it is possible that the lexical blocks with split address ranges can result in buggy behavior on Linux as well.
