Having many files with same name, differing in case only (a cultural 'thing') is just a mess - there's no extra value here. Do you use case in spoken word ? Arguments of performance or ease of implementation are technical details nobody cares (except devs of course :) ) We just end up living with this decission and there's no easy way out.

Can't you trivially solve this without addressing any of the 17 problems with case insensitivity by just not creating afile.txt and aFile.txt. In TB of data including files from the last 17 years I don't think I have any folders like that.
