Yes, good point.

Touche.  I should have said "many contemporary computer languages".
We can list languages on both sides or leave both out.

Case insensitivity also goes against the intuition of many newcomers.
I didn't mention this because I know you felt otherwise.  We can give
both sides or leave both out.

Allowing something is not the same as encouraging it.  Whether it
is confusing is a value judgement---some find it so, others do not.
For that matter, some find case insensitivity confusing, and some do not.
Also, some projects implement case-sensitivity and continue to make use
of it.  Again, we can mention both sides or leave both out.
