For you, perhaps, assuming that you are correct in your implicit belief
that you do not constantly rely on one of these breakable parsers. Me,
I'd rather not risk finding out.

If, by "rediculous", you mean "common engineering practice", then yes,
it's quite rediculous. Best to normalize line endings, then use file
size + CRC to compare - the odds of this failing are sub-negligible,
whereas file timestamps are notoriously unreliable.
Better question - what would be the benefit of... no, no, I know better
than to ask...
