There was a requirement to allow source to be represented on machines
with a limited character set; for example, '%' could be used instead of
'"', and ':' instead of '#' in based numeric literals; see Annex J and
J.2 in particular. However, this did not make programs using '"'
illegal, while a program with 2 identifiers identical except for case is
illegal, so this doesn't appear to be the reason for case insensitivity.
