I think the above is just a correction of an old error where the
old value is kept for compatibility. As I think this stuff has
been there from the beginning, I'd be very surpised if they'd
sacrificed type-safety for the sake of compatibility with the older
version. It would have been easier to leave it.

However, thinking about it, if there would be a definition in
another .swi file (not that unnatural for a message type) it would
be difficult to generate an enum-type from it since the definition
would be split in several .h (or whatever) files.

Maybe it is actually better as it is.
