Given that it's Dan B, it's unlikely to have been to support Allegro
mlisp, but it's a nice side-effect.
I'd be sorry to see this change.
The only thing I can think of about the non-downcased strings is that
the assumption was that the strings are inconvenient enough that they
are effectively a way of specifying an intention to override the default.
But that's just speculation. Could equally well be a simple oversight.
