No, it emphasises that there's no reason to use NTFS unless you're mounting a windows drive, like I said. It does not imply anything about the "nicheness" of the one usecase, although, yes, it in fact is super duper niche. Being niche does not mean unimportant.

Most all linux systems will never see an NTFS formatted partition.

This isn't an argument against increased compatibility, which is only a good thing.
