Hmm, that's not what I recall and documented in
target_read_memory, etc.

  /* Dispatch to the topmost target, not the flattened current_target.
     Memory accesses check target->to_has_(all_)memory, and the
     flattened target doesn't inherit those.  */

And indeed, if I tweak the patch to drop that hunk,
that's still what I see.  What recursion did you see?
