> Case insensitivity is only seen as "rustic" because C is case insensitive

One thing people discovered eventually - case-sensitivity is language-specific. It is easy so long as you assume everything is in English and 7-bit US-ASCII, but once you move beyond that assumption, it becomes significantly more complex. An easy way to avoid all that complexity is to not do it.

People also forget about the related notion of accent-insensitivity - again, if all you support is English, you can ignore that, since English hardly uses accents
