Be realistic. If '\n' is the default line terminator, then flex will
cover most cases. For the rest of the cases, you neither gain nor lose
anything compared to the current scanner.

I don't know how you can say this. The best part of column tracking
is that bison does half the work for you! The other half of the work
requires thankless fiddling with line/column counters in flex
actions.
