You are correct.

I don't see that Allegro (ftype.htm) supports boolean types. I don't
recall seeing other UFFI supported platforms supporting boolean types
either. Most of the FFI's are at the C level and a boolean type is not
a concept in C.

That said, something like this could be grafted on to UFFI with
get-slot-value to do automated translation, but I personally don't
have a need for such functionality.
