The main use cases that were considered as far as I recall were credit
card numbers and other bank numbers (we originally considered type=cc but
that turned out to be more locale-specific than expected), social security
numbers and other formatted serial numbers, and username fields that
exclude certain characters.

The feature sets are different in many other ways. This is hardly an
exception. For example, <textarea> has no list="" support, cols="" works
differently than size="", the default value is set differently, <textarea>
doesn't support autocomplete, etc.
