The allocate ended up with CFFI being passed ':float, which really made CFFI unhappy.

Strange, it works for me.

UFFI> (allocate-foreign-object :float 16) #<A Mac Pointer #x302E30>

Also, ':float shouldn't be a problem:

But a similar hack on deref-array did not fly [...]

If I understand the UFFI docs correctly, I think your code is not correct UFFI, since deref-array expects an array type, not the type of the array's elements. So, def-array-pointer would be necessary to define the array type.

cffi-uffi-compat seems to be a great way to find bugs in UFFI code, heh.
